I have a 1989 Toyota Pickup extra cab. I have been having a problem with the truck just shutting off at different times. Doesn't matter what the temperature is or how long I have been driving. It just shuts off. Any advice would be appreciated. Thanks

 

3.0 or 22R or 22re?
auto or stick?
Miles on truck?

 

Had this happen when my negative came off the battery a few times.

 

More info as stated above and have you done any kind of diagnostics yet?

 

Is it turning off like you took the key out or is it dying off? If it's shutting off like it does when you take the key out I would start with the battery cables also. If it's dying out I'd start checking for vacuum leaks.

 

Check the IACV, possibly some adjusting to get the RPM's a bit higher during idle, mine would die on me while slowing down and I adjusted it, problem fixed! it might not be the case with you as there are many reasons for a car to die, as well as more info is needed

 

Take the battery cables off and clean the battery posts with sandpaper until they're nice and shiny. Soak the cable terminals in water with a spoonful of baking soda to remove corrosion, and then sand the terminals down to bare metal so you've got a good clean connection with the battery. If you get battery acid on your hands, remember not to pick your nose or wipe your hands on your jeans.

 

Make sure you pick up some dielectric grease to put on the connections too. It will help keep corrosion away which will ensure you keep a solid connection.
