MY VAN RUNS GREAT BUT RECENTLY I HAVE THROTTLING PROBLEM THE WILL CUT OFF WHEN STOPS OR EVEN SOMETIMES WHEN I PUT IT DRIVE I CHANGE PLUGS,WIRES,ROUTER, DISTRIBUTER CAP,TPS AND THE AIR CONTROL VALVE AN TI STILL HAVE THROTTLE PROBLEM PLEASE HELP THANKS IN ADVANCE

We keep replacing the battery but none of them have held a charge. The auto shop says there's nothing wrong but we have to charge the battery if we want to use it. Sometimes we can be somewhere and the van has ran good up to that point but if we turn it off, it won't start again. I am not sure if it is 5.7L V8, or 5.0L V8.

My Vandura runs perfectly when first started running in Open Loop and doesn't miss at idle or at high RPM. Once the van reaches operating temp and goes into closed loop, it hesitates and backfires when pressing more on the pedal. A very slow increase in RPM will not cause it to backfire or miss. This is all in park position and when it is in drive, I can't get it out of the driveway without backfiring or stalling under a load.

I added Techron to it last year and the problem went away after 2 hours of running in the drive with some idling and accelarating. This problem din't occur again for the whole summer until last fall and Techron didn't work this time.

There is no engine light or any indication there is a problem. What is causing this?

i have a gmc van 1989 it idles fast put in plug wires tps and map sencer and it steel idles around 2000 rpm

How do you install a netraul safety switch on a 88-91 gmc van

I have a 1994 GMC Vandura 1500 and the radiator recently froze. It was also low on oil. We managed to thaw the radiator, put in antifreeze, filled the oil. I was able to drive it the next day, all day, and then, the following day we were able to drive it for about 30 miles or so in town. On the way back home, it shut down again. I had the battery tested and replaced. It started fine and I drove it this morning to take my daughter to school. I got back home, it sat for about 4 hours and I had to go back into town. About 2 miles down he road, it shut down again. I'm not sure if we damaged the engine at all during the freeze of the radiator/low oil. It sounds like crap, but I assumed that was due to the muffler being damaged during a tow. Now, I am thinking it may be due to the engine. It does sound like knocking but like I said, I thought it was the muffler, as it did not make any odd noises until after the tow truck driver "dropped" the back of the van on my driveway when he was unloading it from the truck. It was on a roll-back truck and when he was unloading it, it slipped and the rear end of the van hit the pavement. I assumed that was what was causing the noise, as the muffler pipe was then cracked. Any ideas on what could be going on? Could the muffler pipe being cracked cause something to shut down? Could we have blown the engine? There are no check engine lights coming on or any other lights other than my airbag/abs lights which have been on for a long time.
