Engine Performance problem
Dodge Ram V8 Two Wheel Drive Automatic 110000 miles

My 2000 Ram 3500 is a van conversion. Yesterday the engine light came on. I bought this vehicle used and don't have a service manual. Van still seems to run OK, all gauges normal--had it serviced by a Dodge dealer about 1000 miles ago.

When I start the van cold, the engine will rev up and down until it warms up some, then the rpm's will stabilize. This problem is worse when the weather is cold

I noticed yesterday that, when idling, the van moves jerkily (not smoothly) in either drive or reverse. It had not done that previously.

Thanks in advance or any help

Have the computer scanned for code/s-you have a problem within the engine management system that caused the CEL to turn on-This is your starting point of diagnosis,finding out what's going on

Thanks much for the suggestion. I went to auto-zone and they said the light indicated a sparkplug. I think that would explain the other symptoms I've noticed.

Thanks again.
