Okay, I'm kinda frustrated about a week ago me and a buddy put all of my bolt-ons on. Intake, header, cat, pulleys, exhaust. The problem is that when we installed the cat we had to pull out the o2 sensor and when we put it back in we got a check engine light. So we checked to make sure the exhaust is completely sealed and had no leaks, there were none, and i still have a check engine light. Any ideas from anybody.

 

try reseting your ECU. pop the hood and pull off the negative battery for about a couple of minutes then put it back on and start the car, you probably wont have that problem again. car needs to readjust to the intake most likely.

 

also, we need to know what code
