Have you tried running it with the cold start injector unplugged? Sound like it is over fueling.

check your egr.  you'd be amazed how much problem it will give you if not working right.

I would look at having the injectors serviced, could be a leaking injector.

well i re-sealed the injectors and did a general tune-up which made it run great...thanks for the input i wheeled it all night friday night.....thanks again

did you narrow the problem down? i mean what did you replace, clean, or whatever? the info may help someone else.

first thing i did was pull the upper intake and saw that the injectors were very loose in the ports where they go...i went to the parts store and bought 4 injector rebuild kits...its basically all the seals for one injector put them on and put it all back together fired it up and i was running much better but had a fouled(sp?) plug so i put plugs wires cap and button on it and problem solved it runs great....hope that helps...

good follow-thru. It helps others when you make the last post to tell what made everything work.
