sometimes when i am driving either on the highway or around town it doesnt matter my check engine light comes on, but just for 10-20 seconds, then shuts off...is there any way to check the code even while the light isnt on? how do you go about doing so
i have a 94 gt with just exhaust, k&n air filter, and computer chip, but it still isnt that fast, i was wondering the best methods of improving my car's performance without spending an arm and a leg...thanks
