Question about 1991 Chevrolet Cavalier

1 Answer

Car shuts off after driving at higher speeds

I just was gifted my grandfather's 1991 Chevy Cavalier (automatic). It sat in his driveway for about a year undriven before I received it. It ran well before it sat around and it ran well when I was driving it below 40mph. After I took it out on a major road, I made it about 6 miles at 45mph before it stalled at a stop light. It would start perfectly fine, but when I tried to shift it into any gear besides park it would die. After about 15 minutes sitting there I tried to start it again, and it started and shifted into drive perfectly fine. I had it taken into a shop and they said they couldn't identify the problem because it was running fine the whole time it was there. I left the shop and was on a major road again (going 45mph). I made it about 3 miles from the shop before it stalled at a stop light again. People have been saying to unplug a switch on the transmission? But I've also been told that switch is mainly for starting the car, which isn't the problem. Is this suggestion the solution or does anyone else have an idea?

    I've heard that this is a common problem. The car has been kept in excellent condition and only has ~53,000 miles on it.

Have you had the engine serviced ,plugs,filters etc also put some fuel additive in the fuel to help clear any deposit build up in cylinders etc, as vehicle has not been run for a while a service might be required to get running smoothly through the speed range

Testimonial: "My dad had some work done on it before I started driving it. I don't have the details about what was done except for I know that battery was replaced. Its in the shop now but I'm just hoping that whatever the problem is its not going to cost me and arm and a leg."

    i think a service and general check for any perished vacuum hoses etc should see it alright as it ran well before it was laid up for a year good luck ,keep me upto date if you wish

SOURCE: start the car let it warm up drive around for 10

First place I'd look is the mass air flow sensor: remove and clean with a Qtip and carb cleaner. Its a bit delicate so be nice to it. After that, check idle air control to see if it's working properly. Of course, change filters (that's proper maintenence that should be done even when working properly) If after doing this stuff you still have a problem, get a manual and even if you can't access codes, there are specific tests you can do using a decent volt/ohmeter.
I think you got me going in the wrong direction with the trans thing. So, if it's shifting properly while going down the road, leave it alone for now.

SOURCE: 91 automatic Cavalier stalls after stopping

It sounds like the torque converter clutch. Just unplug it. It is the square 4 pin plug on the front of the transmission. Once it is unplugged and you get it unlocked, it will be fine. Just leave it unplugged, it won't hurt anything.

If you are really really lucky, it is the harness on the side of the transmission. Unplug the harness looking for corrosion. Clean and reassemble.
It could be the TFP Switch, wires connecting TFP to PCM or the PCM is bad

Can I install a 4 speed automatic transmission in my 1991 chevy cavalier to get better fuel economy?


I assume your car has a standard shift right now. Automatic transmissions **** up more gas than a stick shift, so I would advise you to keep yor standard stick shift. Just don't go around burning tires and try to keep your motor RPM's as low as possible.
