my engine is bone stock, w/ the exception of a newly installed msd distrib and coil. The motor has a slight stumble under accelleration. It has been timed over and over again. I want to get it running smooth before I start doing engine bolt-ons. Stock fuel pump is running at about 29-30lbs. Plus its not setting off any check lights. Does anyone know what direction I need to go in?

 

You are only getting 29-30 psi at the rail? I would go ahead and upgrade the fuel pump and get a fuel pressure regulator. Replace the plugs, wires, and fuel filter while you are at it. Make sure you have your firing order correct. My brother built a nice 95gt but accidently crossed 2 plug wires and it ran great except for a small stumble and he didn't think about something as little as that. Just do a tune up and double check everything and see how it goes from there.

 

what type of plugs are you using???

 

I'm using motorcraft stock application plugs.

 

have you tried cleaning the MAF sensor?
