Question about 1999 Dodge Ram
Have a 'dodge grand caravan with the 3.0. We swapped motors with a '92 plymouth voyager 3.0 that had been running great. After swapping motors the motor starting running rough and now when it gets to operating temp. she dies, we are able to restart her but foot has to be on gas. We've tried all sensors. The only thing that we haven't done is put different fuel pump on. All compression tests come out fine. Any suggestions. Trying to get fixed in time for xmas to use while other van looks at having trans. rebuilt since overdrive gear went out.
With the difference in years, there maybe a difference in alot of things. I'd start with mking sure every sensor, injector, everything links up properly to the 99 caravan pcm. If it's seeing the wrong info it will be a no go. Sounds like it's thinking it's -40 outside(foot to the floor to start) this indicates the coolant temp sensor maybe screwy. Let me know what you find, and about any other changes or issues.
