Djet computer fixable? 140-160 1972

posted by  someone claiming to be andyknight on  Fri Aug 1 13:22 CST 2003 [RELATED]

I've swapped plug wires and plugs #1 and #2, BTW both of those plugs were a grayish tan color which suggest good mixture and spark, so with 164 psi (good comprssion) reading this is pretty baffling, although I used a known bad injector in #1 and it ran horribly, barley at all, which I took as proof it was at least getting some combustion in there with a known good injector, pulling the injector harness for #1 produces the same results as pulling the plug wire, a very little, but perceivable drop in RPM, pulling 2,3,or 4 produces much more noticable results. The 142 has good power, but I have to coax it to keep it running until it warms up, I've adjusted the dial on the ECU to best idle,
I know the Aux Air valve never closes, so I plug it after the engine warms, I'm getting another one soon, after warmup it has good power but a rough idle, after reading a what you went throught in a effort to get the car running even exhaust manifold temps, I'm experiencing a little trepidation, maybe the head gaasket is leaking when the engine is cold, and retorqing it would inmprove cold idle, anyway I hope you have sufficiently recovered from your surgery to work on your 1800, thanks.
