Question about 2001 Dodge Ram 1500 Truck 2WD

1 Answer

2001 Ram 318

My truck hesitates when the engine is cold. Almost like a misfire on acceleration and only up to about 2000 rpm. Once it warms up it's fine. I changed the cap&rotor, wires, plugs (gapped to spec.), air filter and cleaned the throttle body. It runs better warm, but didn't make any difference when cold.
I was told it could be the manifold temperature sensor or coolant temp. sensor but engine temp. seems fine on the gauges.

Some of these have two temp sensors, one for the gauge, and one for the computer.

Check timing of the engine is right using an engine timing light. Make sure the timing belt or chain isn't worn or slack. The head gasket could also have gone and may need replacing.

Sounds like misfire... Did the 'Check Engine' Light come ON? Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on.
You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem.

88 dodge ram charger 5.2 ltr engine....intermittant spark


I have a 1988 dodge ram charger with a 318 motor with throttle body. It runs really good when I start it up and drive it for about a half of an hour.
But after that when I step on the throttle a little bit, it hesitates. If I let off a little bit, it will go or if I really step on it, it will go also, but if I just hold it there, it really hesitates If I stop, the idle jumps up and down so much it causes itself to stall. It seems to only do this at low RPM's. If the RPM's are higher it's fine

Hesitation or stumble during acceleration


take your car for a tune up
if they are carburetor type motors you may need your carbie cleaned and a tune up
if you clean it your self with carbie cleaner it may increase in idle speed this is nothing to worries about it is a simple adjustment
with a carburetor type motor they tend to idle higher when their cold this is the automatic choke kicking in and normally it should happen till the car is a bit warmer and the accelerator has been depresses
although a car should idle at 800 rpm my paddok car dose when it is cold it idles at 1200rpm i like it this way as the car warms up quicker as i will not drive a car while it is cold
hope this helps
