Engine/Transmission (1994 - 1998) A little help.........

[DWitcher]

I've just installed a 887/215hp pump that I got back from the local pump shop for a rebuild. Its popping and missing bad on hard acceleration through the exhaust just for a split second no matter where the RPM's are. It's like the first stab of the throttle then it clears up. No problems when accelerating slow. There is no white smoke like unburned fuel. Just lots of black. Timing was set a 5. 7mm from #1 TDC which I was shoting for 15. 5* to 16* I have the Stage 2 injectors, 100 plate centered, 3gsk's set at 3 clicks, Stock(HOT egt) turbo. All new fuel hoses, lift pump and fuel heater eliminated. It ran great before with the 838/160hp pump. What should I be looking for? Thanks, Guys.

black smoke is unburned fuel. Sounds like you have too much fuel. i dont know about the missing or popping on the pump- can you verify that you are truely at 15. 5/16*. Maybe you're actually a lot higher?

Yea, I'm gonna recheck the timing again and see if thats it.

It also stalls very easy. Could that have something to do with timing?
