I have a 1998 5.2L Dakota which just turned 100k miles. It ran fine yesterday, but this morning it will start....if i give it gas, but as soon as i let of the pedal it dies. I have to keep around 700 rpms for it to stay running.

Not sure if this could do it, but i replaced the factory radio yesterday and i disconected the battery, but it ran for over 100 miles afterwards.

The only other thing that I know of that is wrong with it is a rusted gas tank filler neck, which i just haven't gotten around to replacing yet.

Any assistance would be appreciated.

 

Clean the throttle body good will help you out if not its the IAC or TPS

 

thanks cleaning the throotle body did the trick i truly appreciate it
