Could really use some help

[fixkick]

still have the CAT on it?
if yes, it can melt and make no power at high revs. then gets works and no starts, due to engine cant pump air.
if the spark tips are not black, but are cream/tan or very light gray , then its not rich misfiring, just starving for fuel.
fuel pressure is always #1 for fuel starvation then , dead map (rare) or filters clogged in injector, screen (top and bottom screen)
spark timed ok
then vacuum at idle 20" HG and not bouncing
usually the map always work, hose good. never seen a bad map ever, (not crushed)
here they are...



I have looked at the MAP but have not tested voltage to it to know for sure weather it is dead or not. i do know that it is getting good vac.

I have not pulled the injector to check those screens. I will do that.

As for when it has power and when it does not it is very hit or miss. sometimes it does at WOT, at low RPM's doesnt really matter how much throttle you give it until you get it over 3k. typically i have to pump the throttle peddle to get her rolling. sometimes she will run like a champ and others you feel like you have to either get out and push or rev it up and dump the clutch to get it off the line.

I have not checked Fuel pressure yet but did have the regulator out. All in all it seems like it is running very rich and not starving for fuel but i would definitely say it is bogging not misfiring. makes a bogging noise through intake if you have the rubber boot off from filter to manifold and run the throttle with you hand on the TB.
