I have a 03 cav ecotec since i bought it i have an intermittent problem where u step on the gas and it will bogg out like it is getting way too much fuel. I took it in to the dealer several times and they only found one run rich code once . I have found a few other cases the same on the internet . I have put the sc kit on from gm and the problem has returned even worse. I have had all recalls and reflashes. It never throws any codes for the engine light to come on. If i turn the car off and back on it will correct itself but it is hard to do while in traffic. I need help. I have thought about getting a tuning shop here to use hp tunners to tune the sc i thought this might catch what the f$%^is goin on.
Any one have any thoughts or help on this?
