So long story short... Finished the top-end rebuild on my 90 v6, no warping or cracking on the heads due to the profound overheat it experienced as luck would have it, minor scoring in the number four cylinder but nothing to write home about. New gaskets and seals all around, new 300zx exhaust studs on the manifold, timing belt, everything looking pretty clean and keen in general.
So everythings all back together.... Blub blub blub blub blub. Blub blub blub blub blub. Won't start. Try it again, won't start but really sounds like it's trying to catch. So I give it a bit of throttle. Catches and dies. Give it a bit more throttle. Starts and runs. I rev it low for a while trying not to over-do it while the new gaskets are setting in (trying not to keel over from the exhaust and burning gasket in the tiny little cracker box of a garage I borrowed to do the job, my house and garage being 45minutes away from the break down and me too cheap for a tow).
So I rev it low like that til she's good and warm then take my foot off the gas. Blub blub blub... Blub... Blub... Cough. Dead. Start it up again. Can't resist the urge to rev it a little higher. I do... Purrrfection, revs like a bi*ch, sounds gooood. A big ol vroom, no weirdness, good news yeah? Still won't f-ing idle.
Been over everything, computer reads a code 55, no vacuum leaks, EGR diaphragm has good action, everythings torqued to spec and tighter than a nuns you-know what. Plugs look good, number 1 cylinder compression a little low but nothing to be alarmed about.
Little pissed off cuz if this was a carburated engine i'd whip its little hiney. Fuel injection, emissions b.s. and computerized whitsits be damned!
Any suggestions?
