Please HELP!!! ASAP





Well.... ? Inquiring minds want to know if this mystery has been solved..





You have never confirmed that the O2 sensors are not crossed.
FYI the Passenger side O2 plugs into the harness on the drivers side and the Drivers side O2 plugs into the harness on the passenger side.
That said, the "mechanic" could be saying everything is OK but may be ignorant of this fact.
If you take your car anywhere you MUST take it to someone that specialized in Corvettes. And If the shop you took it to is "waiting on a GM scanning tool" you have it in the wrong shop.


Just by "looking" at the O2's how can he tell there is nothing wrong? Has your mechanic installed headers on a C5 before? They actually go criss-crossed, so if they are plugged same side to same side..logically they might look right when in fact THEY ARE NOT. Its just the design.And bad grounds "wasting" a computer is just plain simple BS.
Don't mean to sound like a dik, but we've all been telling you now for how many days to take it to a performance shop, and you just keeping picking out shops to take it to that don't have experience in this type of thing. Heck, even this last place told you TAKE IT TO A PERFORMANCE SHOP.

Yes your all were right!!!


O2 sensors were installed incorrectly. From what the vette specialist told me today they were not supposed to be crossed, but they were! tomorrow I m picking up the car.Thank you for supporting me and thank you all for your advises.
There are two more things though that I would like to hear your thoughts on
First, I want to go to the muffler shop that did the original install and screwed my o2 sensors, and see if I can get any money back out of them, at least the couple hundreds that I had to pay to repair the sensors.
What do you think is the best way to approach this issue with them?
do I really have a chance of getting some of the money back without involving lawyers and such? I am extremely angry and frustrated with that place.
Second problem is ABS system light. the corvette specialist told me that it would be his second priority if he was me to repair that problem.
He said he had a unit at his shop he could sell me and with labor charges it would cost 900$.
I am going to see if I can buy it on e-bay or from a gm dealership
for less. the problem is that can not afford it right now and have to wait a couple weeks.
What am I risking when driving the car like this with ABS lights and traction control light coming on and off?
I personally do not care much about traction control and can drive without but he told me that my brakes could get locked in and cause a serious problem. is he being a little dramatic or it is something that I should be very concerned about?

Take it to the muffler shop. Tell them to pay up or it's off to small claims court.
Do a search. I know someone on the forum repairs ABS modules for like $100
Is the way to go and you can do it yourself and even drive it without the ABS installed.
But first, reset the code C1214 and see if it comes back. You can do it from the dash. There was something in the past 5 pages about the grounds being messed with and maybe that's all there is to it.
What do you think is the best way to approach this issue with them?
Never hand them your original invoice, it will get "lost" quickly and you'll have no evidence of their error. Hand them a copy.
At the first sign they don't want to cover it, I'd begin with "I'm hoping not to have to go to small claims court and the BBB on this..."





What you should have done to begin with was, when you posted this thread here and we where all screamin at you telling you the O2 were reveresed, you should have taken it back to the first shop and insisted that they switch them just to try it at least. You would have saved all the other time and money/hassle that you wasted.
When you try and take them to small claims court, there lawyer is just gonna argue that they were not given a chance to fix it, plus, these are aftermarket headers and not OEM parts they were dealing with. Pluse now you've had 3 or 4 other shops messing with it, how are you gonna prove it was the first shops fault?
You could go back there and talk wiht them and show them what they screwed up and ask for money back, it won;t hurt but again youve already wasted a ton of time and money on this, why waste more. Next time, take our advice and don't keep running around to different shops..live and learn.
http://www.absfixer.com you may save some money doing it yourself, or someone from your area that's a member here may be able to help you.
I decided I am not going to bother and raise the argument with that muffler shop. It is simply not worth it. I am picking my vert from this corvette shop in a few hours and nothing else matters to me.
I also think that my mod fever is over, I will never let anybody (other than a specialist) touch my vette again. Maybe later I will upgrade to a Vararam instead my dual cones and get a real tune on the dyno instead of the predator, and just keep it like that.

Hello everyone.
I read, watched, listened.
02 Z06 ran really bad after exhaust work.
I took back to shop today--requested he do nothing but replace the O2 sensors and make sure they are pluged into the proper side.
As everyone said---they were incorect.
Runs so good now--I can hardly stand it!

Did not have to run around from shop to shop.
Thanks everyone.
