I bought this truck for work from who I thought was a friend. She sold it to me for $300.00 with a non working fuel pump. I changed the pump (new) and was able to get it started. It ran really rough so here is what I've done...
Oil change, plugs, wires, cap, rotor, crank shaft position sensor under the distributer cap, idle air flow sensor, air filter, air intake gasket, exhaust tape around pin holes at welds, inspected for vacuum leaks and probably more I have forgot to mention.
What's still happening...
First it's driving now (minimal)
At any speed I go I get vibration or shaking, not in the steering wheel,(seats, front cab) rather anytime I try to maintain a speed. I get popping, I like to describe it as tho I'm making popcorn as I am driving. Also happens at any speed including, but less of, during idle. No shaking when I apply brakes! I get a rough idle my rpms are roughly 600-700. Sometimes it cuts power completely while I drive, throw it neutral and turn the key, so far it's always started back up. The catalytic converter was thought to be an issue so it was hollowed out, still had the O2 sensor in it but the wires are not attached (broken) damaged beyond repair when hollowing the catalytic.
Sounds to be a very strong engine with a great body and thought I was getting a good deal but now it just seams that I'm putting a lot of time and money into it seeing very little results. Not complaining, I did buy a non running vehicle and now it runs and drives. I just want it to be safe.
