Question about 1990 Buick LeSabre
1996 Buick Roadmaster: Symptoms: rough start, sputters and coughs unless foot is on accelerator then it may **** occasionally while driving. Sometimes stalls at red lights and stop signs or if I am in a 30 mph zone...had complete tune up 1 year ago...today air conditioner started blowing hot then going cool again when it sputtered - did not show hot on dash gauge...Have tried gas treatment and fuel injection cleaners...this problem will seem to stop for several weeks then it will begin again and last for a week or more. Is it my thermostat or a sensor gone bad?
Check the mass air flow sensor (clean both heated wires with carb cleaner and Q-tip). Remember...cleaning does not always work...sometimes they are actually bad. Also check map sensor. Check for vacuum leaks at all hoses and fittings. If engine rpm drops sufficiently, engine vacuum will drop which may have caused a/c malfunction (controls work with vacuum signal) so I wouldn't worry about that 'till the run problem is dealt with.
