ok i put the comptech headers in and when i turned the engine on, i could feel a small vibration. when i accelerate i can feel it more and then the "engine check" light came on. a little later, the VSA lights came on.

what do i do???

is the engine check the o2 sensor??

ive had the vsa lights come on before and i took it to the dealer. they said i blew a fuse or something and they fixed it.

why is my check engine light on?!?!??!?!?!

 

Just from reading on here and on acl.com it sound like the O2 sensor is causing the check engine light.

 

do you hear any noise that goes with the vibration? Maybe you have a leak and it's casuing the 02 sensor to go freaky?

It's probably a good idea to go over all the nuts again with a wrench as they might need a little retorquing.

 

found out wat was wrong. a coil or somethin was messed up. i guess its cause we were takin the back header off at night and it was dark. took it to the dealer and they did it for 30$ since it wasnt under warranty. only problem is , a technician stole my f*cking blue volk racing air valve stem caps and they deny it. im never going to ACURA CARLAND OF GWINNETT EVER AGAIN!!!

now i gotta pay 40$ for new ones
