i think it was an ac delco but i cant be sure. its really weird though. i mean the idle just jumps around up, down , and then itll die. sometimes it will jump up down and stay running though. as long as i am giving it gass it will stay running.
i am thinking that something is causing the rpm'* to drop and something else is compensating like the computer or some other sensor which is why i get burst of acceleration at times. you guys haver anymore suggestions.
I just thought of something, it seems like you're getting intermittent fuel flow. In which case the code you mentioned would fit the clogged injector(*) theory. Lets open the flood gates for all the experts to chime in.
My reaction is also "bad catalytic converter". Have it checked, they're normally covered for 8 or 10 years under warranty by the manufacturer. Any exhaust shop or dealer can check it and fix it under the warranty, if indeed it is bad.
