Sputtering
 

I have a 93 base. upon purchase it ran fairly well with exception of no 2nd turbo action .Anyway I go in replace and tie the vac. lines get everything back together. builds up speed as long as I don't stab the gas pedal which is when it bucks and sputters.

Any help is appreciated!!!!!!!!!!!1

I had this problem, it was a weak engine ground. I reinforced the ground by putting a big ol fat wire from the engine to the chassis and it fixed the problem immediately.

Check your plugs and your wires. If you sputters when you gun it then you'll most likely need new plugs.

Plugs and wires are new ground is good I tied the vacuum lines the hole silicon replacement deal and I have been in twice and nothing appears pinched but I can hear a surge when I release the throttle not the same as a bov release
