I have a 89 Ford Ranger with a 2.9 V6 Fuel Injection. The trouble is that the engine stalls and the RPMs keeps changing at low speed or idle. ????????? Larry

Bad or broken vacuum line. Failing Idle Air Control.
I spent $30 and got a code reader for my 87, it paid for itself first time I used it. The thing checks a bunch of relays, reads stored codes, etc. You need one. Actron brand.
