Vehicle is a 1988 GMC Vandura 2500, TBI 350. When cold sometimes it stumbled upon acceleration. Sometimes it idles high and slams into reverse or drive. Sounds like an intermittent vacuum leak, but now the problem is compounded.
Vehicle now won't start without 1/2+ throttle opening. Runs very rough, eventually smoothes out, but idles low. IAC looked good (until I cracked it overtightening it upon reinstall). Code 15 (coolant temp sensor) is in memory.
Where do I begin with this intermittent mess? Carb & distributor swap?
