Dodge wont stay runnng?


Recommended Posts

1999 Dodge Ram truck 1500 5.9 Magnum Gas Engine

Once and a while when starting, it wont stay running. Cant even back up to get on road. If you keep foot on gas you can keep it running. Usually a trip around the block with forced foot wiil bring it out of it. It does it a very random times:

- cold mornings

- warm mornings

- warmed and restarted

It does not race up and down, just starts and then dies. But as stated, with constant foot pressure, I can keep it running.

Thank You for your Ideas

I should add when it does this you can remove the air tube from the throttle body. Look straight down towards the back of the throttle plate. You will see the air bypass channel and the pintle of the iac in that passage. Use a small screwdriver and gentle push the pintle back towards the body of the IAC. Then try restarting. If if fires up and stays running your on the right track. Fairly common on the older dodges.

If your battery voltage drops below aprox. 9.6 volt the IAC memory will be cleared in the computer and will not know what position it is at. It takes alittle run time before it will relearn what its position is.

Maybe have you battery load tested also.
