2003 Dodge Dakota RPM fluctulation

This can be tough if the check engine light hasn't come on. Has it? Also, have you checked fuel pump pressure? Have you checked for vacuum leaks?

Let me know.

Joe

The Check engine lights has not came on. I haven't had the fuel pressure checked and I has a diagnostic test done which reveal nothing.

WIthout a check engine light, it becomes a guessing game. I would start with fuel pressure. IF you need directions, let me know.

Joe

I had my feul pressure checked and it okay 49.2 psi. Checked vacuum leaks and located nothing. I don't know where to go from here. My truck is running prefectly other then the Flucation with the RPM.

As I stated it I hit a bump the RPM will shot up and then return to normal. Driving on thehighway it shot up and return to normal just to shot up again. Again I lose no engine power.

I have no problem with my transmission and I am not sure this would casue the RPM to shot up.

Therefore, do you have any other suggestion?

Again, the check engine light is not on and have not come on.

Thanks, Dennis

Have you checked the connection to the throttle position sensor?

I have not and will check the throttle position sensor connections today. I'll let you know once I complete checking the sensor connections.

Dennis

Any luck, Dennis?

I had the connection to the throttle position sensor check and everything okay there. Still no check engine light and I am getting ready to have Purge control solenoid check out. I'll let you know the outcome.

I look forward to hearing what you find.
