i got a 94 ranger with the 2.3l and i just bought it and ended up having to put a rebuilt motor in it. it will turn on fine and run for about 20 seconds than boggs down like its gonna die but stays on and after that it will idle fine with no problem after that. when i try to drive it i cant even get up to 20 mph cause its constantly wanting to die like it spuders. it has new wires plugs, battery, alternator, fuel pump and fuel filter. its hard to try and run codes cause my truck is bagged and has no ac or heat so i have all these plugs that arnet plugged in so would take me forever to find what the problem is. Also when i lift my truck up and slam it down then engine will spuder and turn off. And dont know what would be causing that if the fast movement is causing something or what not. Hopefully someone will have a solution cause i have been researching for a long time and havent been able to figure whats wrong

 

Where ya get the rebuilt motor?
