My car doesnt idle smoothly or drive smoothly at all. At idle the car will stutter like its about to die and then come back to a stable rpm. The car throughout 1-2-3 will do the same thing as Im driving. It felt like a fuel problem so I checked my fuel lines. Everythings good there.

Id say its the transmission.. which Ill admit to pushing but I dont really know what it is. Anyone know what else it could be?

 

Could be a ignition system problem. Check the voltages from distributor to the spark plug wires to see if it's within factory specs. If it's not back track the parts and check & test each and every parts starting from spark plug, spark plug wires, cap & rotor, ICM aka ignitor, etc....

 

sounds like you may have a misfire?

 

Sounds like you need some plugs, cap,rotor and maybe wires.

My Z6 ran like crap just because of a little wear on the ignition components.

 

any good way to diagnose the problem fast?

If its just one or two stutters then check your distributor timing, if it feels like you hit your rev limiter and it does it like 5-10 times change your fuel filter. Had the both the probs and each fixed it. Good luck
