I own a 96 3.0l V6 Grand Voyager that developed recently a strange problem: Most days when the car reaches normal working temperature, the engine shuts down intermittently. This may be only one or more brief jolts or it may stay off for several seconds. This happen while driving 70+ mph on the highway. Ones it passes this phase it continues to run normally for the remainder of my 50 mile commute. A few times, the car came to a stop and it took several minutes to restart the engine and a few times the engine did not start in the morning. It appears to be electrical in some way, since adding a charger will mostly start the engine. The battery is brand new and fully charged. The local mechanic does not find anything. Any idea is appreciated. Thanks, Obelix2

The only real clue I have so far is that the engine fires when the ignition switch is in the 'start' position, but it dies as soon as the switch is released to the 'run' position. I'm guessing that the engine electronic control unit is at fault, but it would be helpful to know how your situation was resolved. Thanks, wurz |

Desperately seeking advice on how to fix the cause of our 2000 Dodge Caravan's engine cutting out when coming to a stop light/sign, making a turn through an intersection and intermittently on the freeway with no warning. Problem just started this summer. This issue poses a danger and am afraid of being t-boned or rear-ended. There are no dashboard indicator lights lit, just RPM goes to zero. Have replaced the fuel filter...no improvement. Have taken it to AutoZone for a read and there was nothing on it. We've read on other blogs where folks have taken their Caravans to dealers and the dealer's just scratch their heads. No indicator lights, problem doesn't register on their diagnostic tools. We've also read where it could be the EGR, but have also read it's not the EGR. Other blogs have indicated it could be a problem with the Throttlebody. We can't afford to put it out of its misery and replace it with a newer vehicle so we need to fix the problem soon before we cause an accident.

Replying to: dragon16 (Aug 30, 2009 11:24 am) It may be the MAS (Mass Airflow Sensor) that is causing the issue. I had a very similar problem with a Subaru Outback many years ago, where it would randomly stall (typically approaching or leaving an intersection). No CEL, no other symptoms. I wasted several hundred dollars on "diagnostics" with no success when one mechanic suggested it might be the MAS. I found a used one for relatively cheap, installed it, and never had that problem again. Now, here's the interesting thing.... about five years later, I gave that same MAS (the one I removed from my car) to a fella who had his go out. He cleaned it up (I think he took a carburetor cleaner to the sensor element) and it worked just fine for him for over a year. So, maybe yours just needs to be cleaned?

Replying to: xwesx (Aug 31, 2009 9:42 am) I sprayed the throttlebody last night with trottle cleaner which seems to have helped, but it's too soon to tell for sure. I like your idea and will also try cleaning the MAS. Thanks for the tip! |

Replying to: dragon16 (Aug 30, 2009 11:24 am) 1. cleaned throttle where air comes in - helped a little 2. checked EGR valve, it could stuck open: disconnect the vac. tube from it (put something on the end of the tube to prevent vacuum leak). It will pollute, but if it stabilized then EGR is bad. That was my case - replaced EGR, runs good since.
