New '86 owner with the familiar mods....
A couple of 'symptoms' that I'm trying to understand. Have been searching through the archives for a couple of days so I hope I've done my due diligence and am not asking a completely obvious question.
Particulars - Ambient temperature 60 to 70 degrees (no winter here yet).
On initial crank, car fires right up. Smells a little rich if there is such a thing as it can't sit in the garage for more than a few secs before you start getting loopy. Heavy monoxide.
When running car after initial crank, no boost. Car falls on its face at WOT. Let off and ease into throttle and car will begin to build boost. Sometimes a minor puff of blue smoke but not alot.
Once this 'episode' goes by, car will seem to build boost fine at wot from that point on. Each subsequent full throttle seems to act as expected.
Once car is stopped and cut off, the next time it has more difficulty starting. Almost as if it is flooded. Might take 10 to 15 seconds of cranking before it fires. But afterwards, idles fine and no issues.
I've gone through all the scanmaster #'s and everything seems to be in order. Running about 17# boost w/ no Alky right now. No knock, O2 is good and other measurements seem to be in line. Turbo has less than 1000 miles on it.
To my uninitiated turbo buick thought process it seems like a fuel issue. Too much of it, perhaps. But it is odd that it seems to clear up after the initial failure...Maybe something with the car warming up (car runs around 120/130 initially before warming up to 160).
Please help the newb, and don't laugh too hard at me...Okay, you can laugh, but stifle it long enough to type some assistance :biggrin:

(AND I plan on redoing that ground strap on the firewall).
