Sputtering?

Post by Ricksmx3 »

OK. When i start the car it starts fine but then starts sputtering and almost dies but it dosent. When i am accelerating it goes but it sputters and does not accelerate nearly as fast as it used to. So i am having to drive around like a granny cause it wont go. I am thinking that it might be the spark plugs. Please help.

Just a thought, but have you checked your VAF? Made sure it was hooked up properly, checked for leaks in the tubing to your intake manifold?

Fuel Filter is mounted down on the Tranny, your gonna have to take out the battery to reach it. Try that before replacing the fuel pump.

Thanks for all the help guys i have changed all the plugs and the fuel filter and the distributer cap and button. The problem was three of my plug wires have cracks all the way down them. I was going to replace them but they sent me the wrong ones so i have to wait and order them tomorrow.
