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

 

any help would be good im at a loss here so far

 

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

 

Did that ! Fuel pressure is good and all the parts i've put on have been AC Delco. So now Im going to start to dig in to the engine. Im thinking it mite be the cam !!

 

fixed it

it ended up being the dizzy again grrrrrr all good now

 

Thank you for following up with this!
