All,

I recently bought a 95 Disco with 120k miles. I replaced distributor cap, roder, wire set, spark plugs and ignition coil. I did this as part of a tune up. I was not happy with the idiol running rough initially but now the idol jumps up and down until the truck gets to running tempeture and then it runs pretty steady. I took the truck into the dealer to set the timing thinking that I might have moved the distributor as I was swapping out the roder. The dealer set the timing per the specs but I'm still having the issue.

What can be causing this jumping of the idol?

Thanks in advance for any suggestions.

Thank you for the ideas... I have the large manual, can you all point to the location of inlet (intake system)?

temperature sensor ad the cold starter injector?
