[QUOTE='90VERT5.0]Well...its mostly fixed, tho' there are still tasks remaining, of course. There's always something to do it seems. The principle problem was a simple one, and diagnosed when we used the code reader to check cylinders. No. 1 had a dead (new, but dead) spark plug. My buddy tells me I should keep the plug to remember to keep it simple...lol Hate to tell it, but checked the cats (by unplugging and looking for code) TPS, timing, and a substitute maf (borrowed),and fuel pressure, all checked out ok. Yup, Keep 'er simple...

Do have a need for a vacuum solenoid that goes up-vacuum from the egr. Still coding for the egr. Also had a serious leak at the air pump. Battery... well I looked up my old receipt, and the battery was 8 years old. So a new battery. The old one tested ok, showed full charge on my battery charger, but couldn't handle a load anymore.

It runs pretty well now, still has some minor idle issues. I'll work through emissions stuff and see if I can get 11's...lol.

Its wonderful to have it back on the road....[/QUOTE]



Glad to hear you got it all figured out. It's always those simple things that everyone, myself included, overlooks.

Jeff
