ok// back to the drawing board. need someone who knows more about the fuel injection setup, to jump in here and advise me on the pig rich running/ and whether the sticky valves might somehow draw that response from the computer...… I had the computer rebuilt shortly before the overhaul, chasing a #6 misfire before the bottom end of the original engine started showing its age.... and I took the fuel rail off, took it in, had the injectors overhauled, flushed and screens replaced also about 1000 miles before the original engine came out, and they were given a clean bill of health, by the fuel injection place. could they have a problem that the injection place missed or maybe caused for that part of the problem? engine was rebuilt 100% stock, except for these heads and a 30-over bore job. original injectors. No tune. no cam. no 1.7 rocker arms. some of which I want to add, once I get it running again as it should in stock form.
I have never really liked computer control.
