Getting A Message Saying Emissions System Error: P0171 And P0174

Brought To Acura Twice Saying The Gas Tank Or W/e
Has Happened More Than 10 Times. Whats The Worst It Can Be? If Something Is Seriously Wrong What Can Acura Do
Please Give Me All Your Imput

 

huh? i really can't understand your post, but from what i can gather, you broght the car to acura and they have told you that it is bad gas, right?

 

sorry i was just in a real rush to post, they are telling me its problems with closing the gas cap and that the air and gas combo is not the right percentage. Pretty much its offset with either too much air or too much gas i dont really know. Anyways the emmissions light goes on CONSTANTLY. I have read in earlier posts that other people have had this problem, went to acura, and that was it. No More problems. With me it is reoccurring and i am starting to think there is a SERIOUS problem with the motor. When the light is on i noticed as the message stated to me poor gas mileage and the engine power is NOT there. Please give me all ur imput

 

few questions. DO you use premium gas 91 or higher? DO you clsoe the gas capp all the way (3 clicks)? Where do you buy gas from? How many repair attempts have been made? Have any been succseful? What state/Dealership becuase some just like to feed bull to customers?

 

first off only 93 my car gets nothing else, also only synthetic oil , i close the gas cap 3 clicks all the time, im constantly opening and closing it when the light goes on to try and attempt to fix it, no "repair" attempts have been made, and nothing has been successful since the light continues to appear, and this is in New York and im not going to call out the dealership until unless this problem is not resolved, because i do not believe it is the dealerships fault im thinking its possible i just got a "lemon" and if thats so i hope my dealership either fixes the problem or deals with the situation appropriately.

 

Po 171 and po174 have nothing to do with the gas cap.
p0171 means bank 1 of the engine is running lean
p0174 means bank 2 of the engine is running lean.
The most likely cause is a vacuum leak, it could also be a bad mass air flow sensor or the fuel pump is not delivering enough fuel.

one question: Do you have a cold air intake or is it stock?

 

yes thats it, they said the gas was running lean, no i have stock. Also could that ruin the motor? because i am continuing to receive poor engine performance
please let me know what i should tell acura and what they can do

 

Yes, running lean for a period can burn the valves, etc. > bad for engine.
Give the car to the dealer, say "fix it" and get a loaner. You have both an Acura warranty and a federal gov't-mandated emissions control warranty. The dealership can correct the problem before returning the car to you. Mention that it's otherwise lemon-law buyback time after 3 attempts.

 

so that means the engine can be bad? because i already have 9,000 + miles on the car. and this has occured 10+ times. and NOw im going to look up the lemon law but please explain to me anways

 

to add im also experiencing HORRIBLE production from my car when the light comes on and HORRIBLE gas mileage as well. I have talked to the guy who sold me the car and has told me he has had a problem like this on his Acura which was fixed he also told me that the emmisions sensor is VERY sensative. I believe that is bullshit considering that everyone else who has had this problem has gotten it fixed 1,2,3. Please any comments on how to approach the situation, what you might think the problem is or anything please post it will be much appreciated
thanks

 

Wait- did you buy the TL-S new or used?

If new, it's the dealer's problem to correct (or try another dealership's service department). The "Lemon Law" varies slightly in each state, and there is a federal lemon law as well. In short, the lemon law can require dealers to buy back new cars which have a significant problem (brakes, transmission, engine, exhaust) that cannot be fixed on 3 tries within a 12-month period.

If you bought the car used, can you tell if there were any modifications to the air intake or the exhaust system?

 

it was brand spankin new, so i hope they fix it, or im gunna have alot of problems with them. so i also emailed the person who sold me the car what you all think the possibilities are of it being wrong. and told him i feel the engine not working as well as it did at first and what i experience with the light. any other suggestions on how to handle this matter?

 

ANNOUNCEMENT TO MAKE!!!
THE CAR IS GOING TO ACURA TOMORROW

 

ok so this is what happened.
they tell me that they have to adjust valves and thats all the info they have for now at this moment. so im like ok, somethings def. wrong. Then i get a 2nd call asking if i use premium gas? im laughing now saying of course. Then asks me, are you sure. im like ok yea im sure. she tells me they have to take a gas analysis or something.
what do you guys think?

 

I doubt the dealership would go that far into the diag to test your gas to see what kind of octane you are using, but they might just take out all the gas in the car and replace it with known good gas and see how the car runs from there.

 

they specifically told me they had to do a test, not just to test what gas i use but maybe for other reasons aswell. i dont know

 

The techs may need to do a smog check and analyze the exhaust gases from your TL-- if the valve clearances are proper, plugs are firing properly etc., then a fuel injection or emissions control component may have failed (all of which are covered under warranty).

 

question: will my motor be fine?

 

I would assume so. I don't think the valves were burned based on your descriptions above (unless you were running high RPMs continuously while the warning lights were active!). If it was a sensor problem and the car runs within specs after repair without valve clatter, it's probably fine.

 

they told me that they could not find the EXACT cause b/c the check engine light was not on anymore even though i have saved the messages when it told me what went wrong. Have a feeling i will be posting about going back into Acura
hope not

 

I have a 00 Tl that still runs good & just got another TL-S ... hopefully I won't run into this kind of error messages, but I do have a lot to catch up regarding the owner's manual. Was going to bring the new car back for some bird dropping (barely visible after they detailed the car), but it's nothing compare to this ...

 

so i just picked it up from my dad, THE CAR RUNS LIKE BRAND NEW. Before i was having noticably lagging power and now i feel like im in a racecar. Also before switching gears would bog a bit, and now its just as smooth as my friends 2006 SI. I am just PREYING everything stays good and the adjustments they made cannot be messed up again. Thanks everyone for their help.

now time for some MODS!!!!!! lol

 

What does the receipt say was the parts or labor performed?
Dont leave us hangin!!
And because you kept taking it in since new- any engine damage would certainly be warranty issue

Lemon Law - People- its not just 3 attempts- its that plus over 30 days in the shop- thats Mon-Fri business days, with no hope of resovle.
They dont buy cars back without trying everything first

 

they just told me the valves were adjusted, i will ask mi padre for the receipt tomorrow

 

If I were you I would wait until you KNOW the issue is resolved before you do ANY mods to that car. You don't need to give them any excuses not to fix it under warranty in the future.

 

yea im thinking about not doing anything too it, b/c i want to save some money lol. but thats also a big factor in why i am not going to go through with any mods as of yet

 

Correction:
advised cut not to clear codes, when light comes on to bring car by.
51-1 adjusted valves
part number
ACC OL999-9011A, the description was Coolant (TYPE-2)

the operations where 123505 for .6 hours and cost 58.20
the other 1103A3 for 2.1 hours and cost 203.70

i didnt pay for any b/c under warranty

also it says
Factory COND CODE : 03203 CLAIM TYPE:7 FAIL CODE : 03214
51-1 COND CODE :03203 CLAIM TYPE:7 FAIL CODE: 07406

please somebody let me know what any of this means. i have a feeling it is not fixed at all. since then sometimes when starting my car, my rpm's drop to 500 rpms, and sounds like my motor is going to die, also i am not chirping 2nd gear as much as i used to. one last thing is that today is was cold 50 degrees and had a little trouble starting.
give any imput please

 

also i should wait till my car is running fine to do an aem cai correct?

 

Hi tahtolindo1,

Sounds like you have doubts about Acura fixing all the bugs in your car and now you’re saying you have other issues.

I’m with bhelsdon on this one! Hold off on any engine/drive train mods until your car is completly fixed and running OK or your going to cause yourself a lot more headaches!

Once everything is working correctly, a CAI is a good place to start.

Good Luck and Happy Motoring!

 

you know anything about what they fixed hobbs? if anyone does please let me know!!

 

bumppp, someone please let me know!

 

Hey tahtolindo1,

I am trying to locate and decipher the codes but I don't have total access to the OEM info. You’re going to need some patience here. I'm sure if someone else knows, they will post it!

Is there a reason you haven't asked your Service Adviser to completely explain everything that was done to your car and what the codes meant? You have every right to know!

I'll let you know if I get anything.

Happy Code Decoding!]

 

good thing i did nothing to my car because here we go again with my emissions light two months later
calling them monday and going to have a fun time on the phone with themmm

 

Remember, You get more with honey than you do with viniger. please be nice.

 

your righttt

 

any updates? my 08 TL-s threw this code this morning. I have AEM CAI (for 5k miles) and UR Pulley & ATLP exhaust for 600 miles...

Acura said "bad gas" i only use premium

 

premium gas can be bad gas too...

 

well, i reset the ECU and cleaned the MAF sensor... light went off, i drove it for a while, and no light is on yet.. cant wait to drain this tank of gas and see if it was the cause
