When it does it it usually does it when in idle, neutral, and reverse. It usually doesn't do it when it is in park.

Thanks

Some other things that have been changed were the rotor and distributer cap, spark plug wires, spark plugs, and fuel filter.

Thanks

I checked the coolant temp sensor and it was good. Could it be the fuel pressure regulator?

Thanks

check the fuel pressure instead of playing guessing games, fuel pumps can do all sorts of weird things when they're going out.

If i remember right TBI systems should be around 11-13psi
