My check engine light keeps turning on and off while im driving, but never stays on, i kinda wish it would so i could pull a code on it, but since it wont im a lil stuck, it seems to turn on as soon as i lift off the throttle or push the clutch in rolling to a stop, now it doesn't do it all the time but two or three times a 10-15 min drive, and ive also noticed that it only does it when i get on it a lil or a lot and then lift, but normal cruising is fine...? Mods are trickflow set up (intake, heads, cam), maf, tb, plenum, cold air, 410s, tune, etc...

There are 2 different kind of codes... There's a Continues Memory code that even thought the light is not on there still might be something there. I say run the test and see what you can find. Here's a couple links that can explain it more. If you browse through the first one you can find what all the codes mean.

Good luck and pm me if you need any help with those websites or whatever. -JM

yea forgot about those codes, we use to call them soft codes, but anyways found the problem, said it was my IAT sensor, turns out when i was giving the car a lil gas the motor was rockin just enough even with the new upgraded motor mounts to make the IAT sensor hit the shock tower and i guess break contact for a split second, so i adjusted the c&l intake tube a lil and problem solved, thanks again for the reminder
