i was just driving along, the car had just warmed up and was running pretty good. i downshifted and pulled it to about 7800ish. i look down and see the CEL on and i immediately let off and prepare to stop. engine made no change, no apparent loss of power or change in the engine at all. it still revved all the way to redline and everything. only thing i didnt chaeck was if VTEC was affected at all. luckily i was close to home so i turned around and went back home. i didnt nessesarily baby it on the way home, it was running normally. CEL was on the entire way home. when i get home, i hopped out and popped the hood and looked around for anything out of the ordinary like sensor plugs that could have popped off or anything...nothing. everything looks just how it should be. i shut the engine off and put it back into the ON position to pull the code...no more CEL. WTF? so then i turn the engine back on and rev it a few times, still no code. so what can cause this to happen? im completely baffled. i wish i could've pulled the code and found out what it was. anyone?
