it was running fine and then it started to have a miss and when you snap the throttle it will some times die and other times it will stumble along. But if you bring the rpm up slowly it doesn't miss a beat. It also is hard to start any help would be great
here is a list of what has been replaced in the last year or so, spider injection (twice because the first one blew the pressure reg out) distributor, cap, rotor, wires, plugs, maf, coolint temp sen, timing chain, o2's, upper intake (was flexing causing a vacuum leak) iac, egr cps, (because i broke it oops)
Thanks mike

I'd put a fuel pressure gauge on it and see what it says. Key on, running in place and tape it to the windshield and drive it. This should rule out (or not ) a fuel, fuel pump issue. Didn't see where you did this-if it ends up being fuel pump, buy quality like AC Delco. Jerry
