Hey,
My service engine light came on at like 14,800 miles. I have intake and exhaust. Then like at 14,900 i dissconnected my battery and the light went away for like 5 miles then came back on. i thought it just did this around 15,000 miles so at 15,100 i dissconnected the bat again. the light stayed off for like 10 miles and now its on again. Do you think its the O2 sensor? How can i find out and fix the problem. If it is the O2 where can i get one?
thanks
nick

 

Tighten your o2 sensor its probably loose (check both of them) same problem happened on my friends RSX type-S

 

go to pep boys and have them run their free scan... if it comes back your o2 then mess with it... but this way you know you are not drivign on a serious problem

 

yeah my car's doin the same thing, i have an intake, no exhaust though... all i know is that sometimes the light dont come on, sometimes it stays on when i start the car, sometimes ill just be driving and it comes on outta nowhere... oh and another thing, every rare now and again the damn car wont start!!! i turn the key and it just kinda goes duh-tuh-tuh-tuh-tuh-tuh-tuh-tuh-tuh-tuh-tuh-tuh-tuh-tuh-tuh-tuh... and never starts... WHAT'S THE DEAL WITH THAT?!?

 

y not take intake off reset cel and then if it comes back on goto dealer

 

Have your ignition system checked. Look at your coil packs and and plug wires.

 

When you reset the ECU, you will erase the error code from the memory. However, your CPU has to go through a complete cycle before the error can be picked up again which can range from a few miles to as many as 80 miles plus. So, although it looks as if the problem went away by resetting the ECU, it was still there all along. Definitely go get a scan done, will take no more than 5 minutes and they'll tell you what code has been tripped, and you can take it from there as far as fixing the problem is concerned.
