RE: Check Engine Light - 1/18/2008 5:03:00 AM    TheEngineer Posts: 10171 Joined: 1/25/2006 Status: online does it come right back on after you reset the ecu (disconnect the battery). Or does it take a little. Im just wondering if this is an intermittant problem or something thats constant. Are there any performance issues? _____________________________ quote: ORIGINAL: pilsenblue Even tho My car looks great It will never be fast.

Everynow and then it takes it a minute to start up. But when i unplug some sensor right beside,(Right where my ait intake goes in) It starts right up Havent tried clearing the code then disconecting the battery though. No performance issues, the car screams threw knoxville. _____________________________ 140 HP @ 6000 Rpm 133 (lb-ft) Torque @ 4800 Rpm Horsepower is how hard you hit the wall, torque is how much of the wall you take with you (in reply to TheEngineer) Post #: 3
