YouTube - Grand Prix engine trouble (READ DESCRIPTION!!)
When i accelerate the engine hesitates with the rpm's dropping slightly then back up. The whole car jerks when it does this. In the video it doesn't do it till i put it into auto stick after the 3th turn when it gets to around 3-4k rpm. Replaced o2 sensor, ran injector cleaner through, replaced air filter, but im thinking its the wires? if anyone could verify this it would be very helpful!
*fast forward to about 59 seconds, it does it at about 3.5 - 4k rpm at 1:10ish
