I just got my oil changed and i have 39k miles (2001 cls). When I got my car from the dealer after changing my oil it felt a little wierd when ideling, like it was weak and the idle sometimes droped to 500rpm very quick. Today (2 days after) as soon as I started I drove off because I was late. The car was warmed up allready because I was driving it a few minutes ago so i started it and drove off within like 5 seconds. When i got half way down my block (30 sec drive) my check engine light, traction light, and VSA light all came on. Ontop of that my car is ideling very wierd like it is barely staying alive. When i come to a complete stop the rpm drops to 400 and almost shuts off and then it goes back to normal again. Does anyone have any ideas what this might be. I was thinking that maybe it is the IAC???
Thanks guys.

I think that is a sign of the tranny going.

shit thats what my buddy said over the phone too (he has the same car).... i just changed it around 30k miles though WTF!!!

GenXET

yea, irregular idle is a dead egive away to IAC, that will more than likely be your problem.

blueglows

would they say anything if i have I/H/E.... i have Acura Care

typeR

just goto any auto zone or pep boys and get the codes read and tell us what they are before you do anything...sounds to me like something got un plugged considering this happened immediatly after an oil change

VeeralS05

had the same problem... my o2 sensor was out and my PCM was bad...so I dont know.. take it to the dealership

thatONEguy

As a NOOB what is IAC??

phipark

I'm not sure that those lights would come on for the IAC. Before anybody jumps to conclusions, just get the code pulled.

i brought it in to the stealership...let see what they have to say about my car heaving headers/intake and axel back muffs
i dont see what they can say about the intake and headers if it is only happening when i idle... otherwise it is fine...

blueglows

ok well they said that it was my 02 sensor by my headers and they can not do it under warranty because i have aftermarket headers so i have to p[ay $310. What should I do?

fsttyms1

Tell them to get bent and prove that its caused because of the headers.

Other wise buy it and install it yourself!

daniel951

o2 sensor are easy to replace at least on my other vehciles. unscrew and unplug it and screw and plug in the new one. Might be kinda of tight.

blueglows

yea i know they are easy but i want to bust Acuras balls because everyone knows that its acuras fault and not because of the headers.....
Listen to this best part. I call up the dealer and long story short i asked him to tell me exactly what happened and what was the problem and that if it is the headers then he has to prove it that the headers caused the problem before he says that the headers void the warranty. His response was for me to tell you what is wrong you have to pay us $94 labor and it says in your owners manual that if you modify your car then it voids your warranty and that i dont have to prove anything. I was like ok fucker ill be calling up Acura (but without the fucker part) and we will see how much you have to prove and not prove. Now the only thing is that i want to get it done soon because Acura Client Services takes a very long time to answer you and deal with it so i dont know what to do because if i fix it myself i have no proof to show them what the problem was. By the way how much is an 02 sensor?
Thanx for the support guys.

blueglows

you know what... something does not make sense here... why are they going to charge me $310 to change an o2 sensor if the part only costs $20 and its an easy DIY job? Do you think that it could be my IAC valve and they dont want to do that under warranty so they are telling me that it is my o2 sensor and charging me $310 so that they can fix the IAC valve not under warranty?
and how could just an o2 sensor set of trac ligh vsa light and CEL and cause the car to idle wrong... i thought that the o2 sensor is just to show that air is flowing and does not cause mechanical defects...??

typeR

you know what ...you could goto the above mentioned auto parts store have the codes read and we can tell you how best to proceed...or just take the dealers word for it...up to you

o2 sensors can get pricey, most expensive for our car can get into the mid 100s at most, but more than likely you can find one online for half that. i woud invest in a scan tool or just get the codes pulled. theres a good chance there is a post here with the same codes.

blueglows

yea thats what i am going to do... how much is a scan tool and how hard is it to use?

typeR

a scan tool is about 50-100 for a basic one ..pep boys or auto zone will read it for free ...as far as how hard plug it in under the "not an ashtry" and press enter

GenXET

o2 sensor is actually quite expensive...you can get them at Autozone or Pep Boys for about $60 - $70 bucks for the universal one which you have to wire the o2 sensor yourself, or you can get the one made for your car for about $120 - $130, this is will be simple plug and play. You will have to know which one, the one on the headers or the cat.

For the code scanning tool, you can go to Autozone, I believe they scan it for free.

As for taking it to the dealer, if you replace the headers, there is a higher chance for the o2 sensor to get messed up, so I don't think they will replace it for free. $310 is actually ok, considering the part they charge is $150, and probably take an hour.

doesnt take an hour to replace either of the o2 sensors on the exhaust end. 20 mins max.

GenXET

I was saying if you take it to dealership, they will charge 1 hour of labor, simply because they will count all the time that was used to drive/park your car, scan the code, file the paperworks, go to parts department and get the parts and walk back to change your o2 sensors, then test drive to see if the light still on and many other useless processess. That is how they make money.

typeR

acctually they'll charge one hour labor based on just one thing...and thats what the book saya to charge ...if it say 1.2 thats what ou'll pay doesnt matter if the tech only need 15 minutes to do it

blueglows

ok here is some great info... first i am going to get the codes pulled up and see if it is the o2 sensor but i am pretty sure it is now... then i will buy it from acura since it is a plug and play and do the job myself... but here is the best part... i called Acura/Honda to ask them what they can do for me since my dealer is denying warranty work simply because i have aftermarket headers and would not tell me if they caused the problem or not and refused to prove...Acura/Honda told me that i would have to call Acura Care Warranty and speak with them. So i called Acura Care and i told them my situation and they said that i have modified my car by adding aftermarket headers therefore the warranty does not cover the o2 sensor. I told them about the ACT that states that they can not void my warranty on a certain part just because i have and aftermarket part linked to it and that they would have to prove that the aftermarket part caused the problem. His reply was that they did not have to prove anything and as long as i have modified my car then the warranty does not cover that part. I told him again that they can not void my warranty just because it is aftermarket headers that they would have to prove it and he kept repeating that they are not voiding my warranty, they are just "not covering" that part since i have modified my headers.

This means that anything that goes wrong with your car and it happens to be connected to an aftermarket part then your warranty is voided... or "not covered" under warranty.
The guy was like a robot and liked to play word games by saying that it is not voided but it is not covered by Acura?
So now the only thing left for me to do is either sue Acura Care or just fix the damn thing myself or put the original headers on and send it in to a different dealer.

blueglows

another thing that i forgot to say...i need an opinion...
Should I take the Megan Headers off and go back to stock or should i just leave them on even after i fix it. The headers are ok because they do give me a lot of power (20 ish) but they do hiss a little and i dont want to hear more BS from Acura. (And yes i know i should get CT headers and CT everthing but i dont have that much money.)
