1989 dodge dakota, 2.5L, 150k+, manual
Engine starts and runs smoothly for several minutes then revs for several seconds and dies. If I try to restart it will backfire and i have to pump accelerator
to keep engine running.
Replaced oxygen, idle throttle sensors with no change. Could this be computer? How can I know for sure? Thank you for any help.

Try check the coolant temperature sensor return signal to the computer. The CTS comes in play during initial start up. Its like your choke on a Carb. engine. Further it could be the O2 sensor/s

Suggested Repair

Check the coolant temperature sensor return signal to the computer, since it controls cold-start enrichment similar to a choke. Also recheck the oxygen sensor circuit, although the oxygen sensor was already replaced.

Conversation Summary

A 1989 Dodge Dakota 2.5L starts and runs smoothly for several minutes, then revs briefly and dies. Restarting causes backfiring and requires pumping the accelerator to keep it running. Replacing the oxygen and idle throttle sensors did not help. The expert recommended checking the coolant temperature sensor return signal to the computer and also considering the oxygen sensors.
