I bought my 1990 6.2L suburban three years ago. Drove it only 20 miles and next time I used it the main wiring harness behind the engine block melted down. I suspect squrriels had something to do with it. Before the melt down it would blow alot of black smoke. I thought it was the EGR valve, so I replaced the intake manifold with a "J" model.
Finally I have finished splicing the wiring back together and got it running again. Now however, It still blows alot of Black smoke from the left side ( the one I can see easily) and it seems to miss fire just slightly in time with the smoke. When trying to get it started I noticed Black smoke chuffing out of the exhaust pipe. I figure the injectors must be leaking. Does anyone have any suggestions besides pulling the injectors? Thanks.
