2000 Dodge RAM 1500 Van, Hesitates and misfires after initial startup

After starting, the engine runs fine for a few minutes but hesitates and misfires. Turning the ignition switch to off and back on before the engine dies resets the run condition without hesitation during excelaration and running.

SOURCE: vehicle hesitates when during acceleration runs 2005 lincon ls

Got a Check Light on dash?
Got any stored codes?

Most likely you have a COP Ignition Coil going bad.
Have the TPS Sensor checked also. I would prefer a scope trace, to a voltage reading

You can expect at least one part failure a year on the LS I have a 2004.

Got codes--give them to me,I'll help you out.

SOURCE: Engine runs fine when cold, hesitates when warmed

The EGR valve is closed when the engine is cold and should open when warmed up. Have all componets check to see if they are functiong correctly. Auto Zone provides a free computer scan at no charge . They will avise you what is in need or replacing and how much for the part. These parts are easily installed too

I had a similiar problem on my 1999 Dodge Ram 1500 Conversion Van. It ended up being a partial collapse of the catalytic converter which didn't allow adequate exhaust. The problem only showed itself because I could not get over 55 mph going up a small hill.

2004 dodge caravan 2.4 Hesitates during Acceleration and at idele


You should definitely replace the fuel filter though this probably won't fix your hesitation. It wouldn't hurt to replace the spark plugs this is usually the culprit on these engine. I have the same engine in a '99 caravan and found the for some reason the spark plugs on cylinder 3 and 4 loosen up after one year and cause a misfire between 45 and 50 mph under load (when mildly accelerating).

I think you're describing a classic case of "hesitation." Basically, the engine hesitates when you step on the gas. I would start by checking the timing with the engine at operating temperature to be sure it's within spec.
