SO now it runs good? Well let me know something! Did it run bad only when cold? Like the rough Idle? OR when it warmed up a little it started fine? Mine is crappy when starting cold. Rough Idle and then when it gets a little warm seems normal.

Let me know...Jess


It ran crappy all of the time.Yours is probably the cold start system. Warm up regulator or the cold start injector. The cold start injector is easy to test. Just remove the two securing bolts on the intake manifold and take the injector out. Be sure the engine is cold. Hold up to a glass jar and have a friend turn engine over. If injector sprays out a good spray pattern of fuel then it is okay. If not, replace it. How to check the warm up regulator is beyond me. I just replaced mine. I think the one that I have now needs to be adjusted. I might wind up taking it to a shop. My idle still a little eratic. It's something with the control pressure. I don't have the proper tools. Hope I helped a little bit.
Good luck
Daniel
