clutch switch is bad
engine stalls at low speed
Your engine produces torque(turning power) and revs, and these are related. You can't get more than a certain amount of torque out of the engine at a given number of revs. If you hit a slope in the wrong gear/at the wrong speed, then forcing the car forward will require more torque than the engine can deliver, and it will stall. It's very much like trying to ride a bike uphill in the wrong gear.
Low RPM. Gear is too high for travel speed
In a low gear is better than any other on ice. low gear is the best choice it allows you to slowdown with the engine and have more control.
Not sure when you say low speed. Not knowing what your driveline ratio is I will just use some basic numbers .If 20 MPH is your speed and you were in first gear your engine RPM's would be 3000, if you were in second gear at 20MPH your engine RPM's would be 2500 , if you were in third gear at 20MPH your engine RPM's would be 2000. A difference of 1000 RPM's from low to high gear. Lower engine RPM's less fuel used.
Probably a clutch, but might be a problem in the trany.
you are going too slow for that gear your engine has very little torque at low rpm
Where is the best place to park your ATV after shutting off the engine
maybe your idle to low, if it continues, I have the fluid injection relay switch replaced.
First what motor is in the van? Than tell me what it does before it stalls or you put it in gear. There many different possiables that it could be.
Why engine stalls on 1993 Chrysler Intrepid while driving and sometimes at stops?
