tomorrow i'll switch injectors (checked with stethoscope, all clicking normally / alike) and do a compression test. after going blind reading through millions of posts and threads, i've seen comment that only a leak down will do for this engine, a standard compression test can't be done (?)
high praise and kudos to the likes of ranger, sub, and the rest of the assorted gods that grace this place. (and noobs and twits like me, that allow you a place to show off all that einsteian knowledge! )
i'm dreading a burnt valve; and to wit, is it possible to "do the front head in the car" ( I have a bunch of wrenches, but that's past what I'd prefer to tackle.) I'm assuming / hoping a compression test will tell if it's the valve? (already swapped coils, 0306 persists )
engine runs bad even before the code sets. no other codes (at the moment) i've already replaced the "outer / big" plenum from being ripped in the usual spot, and "leak checked" the vac lines a million times with ether / maf cleaner, etc. I'm assuming the pcm's are good, since they swapped with the coils. fresh AC plugs (and btw, of course the #5 plug snapped off. luckily, and equally rarely in my experience, the plug sheared cleanly off just above the hex / body and took the electrode and insulator clean out with it. after re booting my heart, i was able to take it out with a screw extractor, between beers.
hope i can be as lucky with the six problem.
TIA for all your help, been reading these threads for years now, on my second SLS.
