1998 dakota with v6 and automatic. youhave to run

How do you know this?

Is this a manual or automatic transmission? When was the last time the fluid was changed? If it's a 4 speed and a 4 cylinder engine than that could be the right RPM. It could also be the overdrive is not working. Some SUVs have a overdrive override button on or near the shifter.

sounds like the small ign module ( on left fender , under hood ) went bad . not that expensive . eazy fix . Good Luck

The negative part of the ignition coil is the tach,the tach of the dash is non op

Check your Tran oil pump or torque converter

96 dodge 3.9. Runs fine but manufacturing about a pint of gas on 60 miles into crankcase.

It's designed that why,so you don't damage it. It cuts off at around 3300 to 3500 in park and you say neutral.

I would replace the fuel filter(every 35000 miles),check the condition of the air filter and check out the catalitic converter and feel the tail pipe to see if the flow seems clogged and weak when some one else gives it the gas.
My 2001 had to have a new cat at only 44000 miles. I had them install a "High Flow" type.

4.7? I've had a few of these trucks do this with bad Throttle Position Sensors.

if battery is weak the idle air control solenoid will search for the right position and stall have battery load tested if good put in a idle air control solenoid..
