I know its not a PS, but help...
I have a buddy that has an 89 F-250 with the International 7.3 in it.
Yesterday: He took out the injectors and cleaned them, fit everything back on, and started it up. Before he did all this, no problems, but now there is white smoke coming from the tailpipe. Didnt think anything of it, then dumped some Seafoam down the throttle body very slowly, according to the bottle, and it started sputtering and knocking like crazy, smoking bad. Ive heard they smoke like that though. So he drove it around and felt like it was messing up...its a bit sluggish too.
Hes been having a really hard time starting it prior to this...Thinking the batteries were dead. Ive had to jump him off 4 or 5 times now. But he went to autozone today and they checked the batts, and both were good. Tried to check the alternator, and he was supposed to rev to 2000 RPM. It died on the spot. Couldnt check the alternator, got it started, started to drive off and it died again.
ANY IDEAS??? Seafoam couldnt have done all this could it? It had a hard time starting before that anyway, but after the injector cleaning and PRIOR to seafoaming it was smoking a little. HELP!
