When I accelerate from any gear, it doesn't have the power it had. I replaced the spark plugs, it was about time anyway. It has a faint stutter, almost like it's not getting enough fuel. Any help would be appreciated.

 

did you change plug wires also and if you have a gt/gts the distributor.

and if it is not getting enough fuel you could run some injector cleaner through it, i would probably recommend seafoam as its probably easier

 

fuel filter, mass air flow sensor???

 

Turns out it was the coil pack for # 3 and 4 cyl. Runs like a top now. Thanks for all your posts.
