Well, in the past month, the car has been in the shop about 12 times. My engine is still *lagging* during slow acceleration, and neither Acura, or the other shop I go to can figure out what might be wrong. The problem started when my [check engine] light came on (a month ago) for "insufficent flow" and Acura replaced the entire EGR valve, cleaned the ports etc. (all still covered under recall warranty)

Well, my engine still runs like shit, still lags, hesitates, idles like crap...i've been giving up hope. Acura told me that they coudnt find anything wrong, no warnings, no lights or codes, so they told me to just keep driving it.

Well, Friday, my [check engine] light came back on. I stopped by a local parts store to get an idea of what the issue might be. The hooked up their computer and told me I had 2 codes. (I think they were P0170 & P0171)
It read "Fuel too lean" & "Fuel Trim Malfunction"

I've got an appt. Tue. to get the car hooked up to Acuras computer to find out exactly what is wrong.

Has anyone had these codes before? Is there anything I should know before the Stealership rapes me a new one??!!?? Could this FINALLY be the fix to my freakin engine lag/hesitation issues??

If anyone could help, I'd appricate it....Im starting to lose hope...every week something else goes bad on the car. I guess its normal, I have 144,444 miles on it.

Thanks! -CJ
PS: I JUST got my computer fixed, so i promise to be around more often...including posting some things on the black market, possibly tonight.

 

maybe your ECU is acting up

 

mass air flow meter or 02 sensor maybe

 

crap....so like another $300 fix!?! Damn this car...grrrr

 

dibs on the RH's









j/k. Hope you figure out what it is bro. Also hope Acura doesnt rape you hard for the fix.

 

Hope you figure it out soon man. I wanna shoot pics some time soon.

 

Your injectors may be going to shit. I'm on the phone, but I'll help out in just a few minutes. Affecting your spray patterns. Putting your car into limp mode.

 

Here is something I pulled up from a website. Seems like the answer I gave you was right, or on the border line as one of the solutions:



Q: What is "fuel is too lean" mean in the diagnostic test?

A: Fuel Too Lean is possibly one of the most difficult computer codes to diagnose. Why is that? There are a couple of things that you need to understand first, before you understand what too lean means. An engine to run correctly needs a good balance of air and fuel. This balance is called the air /fuel ratio. A correct balance of air and fuel is generally at a ratio of 14.7 pounds of air to one 1 pound of fuel. If you change either number of that ratio, is will have an effect on the engine's performance. The computer in your vehicle is always working to maintain the correct air/fuel ratio. However, as time goes on the engine wears, fuel injectors become restricted, vacuum leaks happen and sensors may become worn and/or lie to the computer. After all, it is a rough environment under the hood of your vehicle. The engineers designed the program in your vehicle's computer to make adjustments to compensate for changes that occur with time. This ability of the computer is called adaptive learn. But, there is a limit to how much the computer can adapt, all the while, maintaining the ideal air/fuel ratio. If the computer determines that it cannot adapt any more to provide enough fuel for the amount of air entering the engine it will turn on the check engine light and report a code indicating that the system is too lean. Too much air entering the engine for the amount of fuel available. There is also a code for the opposite condition of the engine receiving too much fuel, system too rich. In either case, the code does not indicate a broken sensor, all it means is that the computer cannot maintain the correct air/fuel ratio and it wants help in fixing the problem. I've seen many parts replaced because of this code that did not fix the problem. You'll need a technician that understands and has the necessary diagnostic tools to provide the correct solution to a system too lean computer code.

 

Here is the answer to your Fuel Trim Malfunction that I pulled up from another site. As others had stated, seems like a bad o2 sensor:



Fuel trim is the amount of fuel that is being added or subtracted by the PCM based on inputs from the sensors. The computer is programmed to add certain levels of fuel (injector on-time) based on the sensor input. If after the programmed amount is added, and the O2 sensor sees it it lean or rich, the computer compensates by adding more or less fuel. (adding injector on-time or shortning injector on-time) That is fuel trim-the correction of fuel delivery as determined by the O2 sensor as compared to the factory programmed values.

Fuel trim issues can go either way...rich or lean. With generic data you can see what the problem is and start addressing it. Until you know rich or lean, you'll be just throwing parts at it. (although the O2 sensor is usually the culprit).

 

Damn vulture.......

 

Ha! Yea you guys wish...lol..These are my baby! Searching for over 2 years, and I has just looking for the replica C5 Evo's...and I actually found 5 org. NEW ones...I will NEVER sell these...Im going to baby these like no other!



The sad thing is they are just sittin in their boxes in my basement. I need like $200 because I have to order 1 more tire, and then pay to mount/balance the tires to the wheels....

so that's why there is inflation on the lip and (cuz i want it) that sux man, hope everything works out!!
i thought our engines were bulletproof?

 

if that bullet is a spit wad, then why yes they are

 

i say that cuz i know 2 people with 3.0's in accords no probs. one gets beat like you wouldn't believe no probs, the other has like 220,000miles+ on original motor gets beat alittle, not much.that is one reason i looked at the 3.0cl,everybody has an accord, and the cl is better looking with the same "bulletproof" powerplant.didn't do homework on the tranny but....never really heard bad shit about this motor besides when you shoot laughing gas in it,now the tranny ,don't get me started

 

i know, us 3.0 guys got the tradeoff more power=weak tranny

 

get those damn rims on CJ

 

yea yea yea... we know the story :P

 

So did my info help any? What's the update on this?

 

Well, I went to the shop today and they plugged the car up to the computer. They said the o2 sensor is def. dead. (i think they said it was "bank1"...So its the 1st one, thats on the "A Pipe".) Now here's where I need help. They called both local Acura dealers and both dont carry the o2 sensors for our cars...So its gotta be ordered anyway. Acura wants like $250ish, + then install costs. The total bill will be around $315ish.

My question is, besides Acuraautomotiveparts (for $216) - Is there anywhere else that I could get one for cheaper?!

What about an aftermarket o2 sensor? Has anyone used/tried one for a 97, 3.0?
(I was told that some aftermarket sensors can totaly F* everything up)

So, whats my best option? What would you guys do?
(im hoping this new o2 sensor will totaly correct all my hesitation & lagging issues)

BTW: Cocoa, Thanks for all the info! It helped! Now that I know what the issue is, I just need to know what I should do from here.

Thanks!

 

I have a 2.2 oxygen sensor
they should be the same
pm me if ur interested

 

new? used? can anyone confirm if 97,98,99 & 2.2 or 3.0 are the same?

 

^^ bump! ^^

 

i hate my ack too

 

 

ack,hello wrx

 

 

thats all i can afford, i was planning on gettin an evo but i would be livin with my parents to afford an evo, so 230hp it is

 

must be nice to get stuff like that at your age.

 

ill be 18 working at a factory, making $15 an hr working 12hr shifts, so yeah it'll be a hard earned wrx

 

sorry dude, i didnt mean to steal your thunder

 

great future you'll have. enjoy your nice car and factory work for life. btw, your badges are in the wrong place

 

yeah.....my mom worked her way up in the same company and in 2 yrs shes upto $32 an hr and getting paid double on sundays......and she only works 8hrs a day.
and as for the badges, thats how it came and its getting debadged soon

 

o2sensors.com and pay about $70 for an o2 sensor. And if you really hate your ack, i'll buy it for a dollar!

It sure beats a Chevy!

 

<-----needs an o2 sensor. i hate my car too!!!but only when sh*t goes wrong

acura3.0cl don't forget to pm me im anxiously awaiting your reply!!!
