Here are the symptoms I'm noticing:
'91 Turbo (sorda)
When cold it will stumble and hesitate occasionally. When I drop off of the throttle it even tries to stall. I know it's not the bypass valve causing the stalling, as I just replaced it and I've tested it for leaks.
I suspect it might be running lean as the turbo is pink after a drive even if I haven't been too terribly zealous. I haven't run anything more than base boost lately. (Disconnected APC Solenoid while I diagnose other problems).
Would vacuum leaks cause more trouble with a cold engine or with a warm engine? Could this be a vacuum issue until the car heats up? I have checked all hoses, and they appear to be fine, sprayed carb cleaner all over the place, and it didn't rev up particularly. I may refresh all of them just in case.
Last time I checked the plugs they looked fine. I'll pull them again tomorrow, regap, and report back.
Thanks much.
