I have a '90 Gtus w/ a bridge,roughly 2k miles on port. For a week or two it has been studdering or something when i am driving,while keeping the throttle steady.It starts off smooth and good then it just acts like it misfires.I put new spark plugs and wires in two days ago(all racing ngk).I think its my coil packs not sending enough spark for the port.What else could it be?

 

could be your TPS or an intake leak.

could also be something else, but those are good places to start.

 

Couldnt be my tps,i just got new connectors when i had motor rebuilt.ill check for intake leak,could it be my air fliter is wayy dirty?

 

adjust your tps new connectors have nothing to do with it.

 

Alright,ill do that now.

 

Its not the tps. Checked it out,im still thinking not getting enough spark.
