Hello everyone, I hope somebody can help me. I have a lpg fueled combilift with a 3.0l gm engine in it. Unit serial number is 7602. The problem its having is stalling. It has had dist cap, rotor, module, plugs, coil, wire set, and throttle cable replaced recently. It will start and run fine stationary but intermittently stalls when driving. It always restarts fine. sometimes it will only stall once in a while and sometimes it will stall every few feet. Right now im thinking crank sensor? I don't have any manuals with ignition wiring diagrams or trouble shooting info. Any help or literature would be greatly appreciated. If you have any please email to loewen12 at Hotmail dot com. Thanks in advance.
