Mechanics

I RECENTLY BOUGHT A . IT RUNS SMOOTHE, BUT IDLES ROUGH, WHAT COULD IT BE.

1986 Jaguar Vanden Plas • 154,000 miles

The jag runs down the road very smoothly. When I come to a stop/start, it idles roughly. I have plugs, wires and coil. What else can I check? I am new to jags. So your help is appreciated.

Vacuum leaks and the iac system, you may be abler to get a code if you go get a scan done, I would start here.
