Supercharged.. just chg'd the plugs. Check engine soon light comes on
and disappears after shutdown.. can go for days.. can come back on in minutes on a highway compute after shutdown. Two symtoms.. slight hesitation/chugging at low rpm in overdrive @ highway speeds.. 50 mph range.... and I note it seems to ride system is booting more often (slow leak..?). Dunno if the last item can give a code.
Buick dealership sez the computer can read a code... repair dude sez most often you need to bring it in with the light on.. ie.. "soft code".. Hence I've hesitated to spend the computer time $$. Buick dealer just went under.. the Buick dealership now I have low confidence in.
Appreciate any advice.. Thanks!

1991 buick lesaber, same deal only the light is on for a minute goes out for a few and then back on again. No drop in performance and no pattern to light. (comes on at idle, cruzing at 70, during excel, braking - doesn't matter - just intermittant light at any time)
My 2008 Buick Allure is burning oil, we did check list for the last 4000 5000 km and every time they added about 0,5 l of oil. Very low milage only 57000 km. Have this problem almost from the begining , is there any chance I can fight with dealer to fix it under warratnty since they new about the problem?
