My 98' Jag runs great. However, at idle the rpms seem to pulse ever so slightly. At night its a problem because the lights actually flash in a rythmic pulse with the rpms. I'm guessing maybe 50rpms. Any idea's also what should the idle rpms be and is there a way to adjust them up slightly. Thanks for your help. P.S. Had it to a Jag dealer and he was scratching his head. After replacing some corroded cables he said the lights are brighter but still flash at idle. He wanted to TRY a new alternator but I think if it was the alt. Codes would show up. The check engine light is NOT on and it's not spitting out any codes. Any ideas. Thanks Mike
