Ok before I put the LT4 motor in my car I still have to drive this piece V6 around, well I started earlier today and it started shaking and when I hit the gas it hesitates and sputters and when I gave it more gas it popped like it was misfiring. I bought new plugs and wires and changed them and it is still doing the same thing, Do you guys think it can be the timing?

 

have you checked the fuel pressure at idle and wot ?

 

Yeah all that is fine... I got it running right... I started it back up and took it for a spin and its running smoothly again thank god... Its funny I have a 95 with 37,000 miles on the motor which im gonna end up selling the motor and tranny
