Trouble Spots
Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search
for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested
solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer,
however, we have our own expert looking at additional vehicle problems.
Cold-starting problems:
New valve guide seals should eliminate the blue smoke from the tailpipe during cold starting. (1990-93)
Doors:
The sliding door is hard to open or close, or does not glide smoothly because various parts are out of adjustment. (1990-93)
Engine misfire:
The engine speed may flare during downshifts between third and second due to a faulty transmission control solenoid. (1996)
Engine noise:
A knocking sound from the engine may require either an oil filter having a built-in check valve, a revised PROM, or replacement of the main bearings. (1990-95)
Engine noise:
A whooping noise coming from the engine may be caused by the exhaust valves sticking in their guides. New valve guide seals should correct the problem. (1996)
Engine temperature:
Overheating and coolant loss may be due to rough surface on radiator filler neck. Neck should be sanded smooth and cap replaced. (1999-2000)
Hard starting:
The fuel injector wires tend to get pinched when the air filter is reinstalled. (1990-93)
Transmission leak:
The rear seal on the transmission (extension housing seal) may leak on vans with a one-piece drive shaft. (1990-94)
