MAF code
P0100 MAF sensor
P0300 Multipule misfire code.
The misfire was because the former owner had put two plug wires on the opti backwards, I cleared that code and at the same time I cleared the MAF code.
The reason I looked at for codes is because my car drives great cruising around and when im sitting still reving it up to 4500-5000rpm but when Im giving it hell driving under a load, sometimes it starts to have ignition break up I believe! It seem to have stop after I cleared the code, but the break up came back after a couple of times of restarting the car, but no codes are stored.
You think the MAF would cause Ignition break up?
Has new Opti, plugs, and wires...
