I have a 2000 trans am m6 and i just put pacesetter headers (with emissions) and a off-road y pipe, I also did a plug change to NGK and wires. For the o2 sensors after the cats I used a o2 sim., but here is the problem since this was all done the car jerks a little under exceleration. Could it just be a loose plug wire or what it feels like it is missing but their are no engine service light on so any ideas would help.
