CADILLAC DTS ENGINE PROBLEM

2003 Cadillac DTS • 127,000 miles

Car has been driving wonderful. I came home from driving my usual 70 mile round trip. Got up in the morning and when I started the car the engine shakes very very badly only when idleing. If I rev the engine it stops until it gets back to idleing then the engine is shaking like crazy. Any idea's?

Either the idling speed is too low or there is a misfiring causing the problem. If the MIL is indicating, retrieve the trouble codes and let us know what they are.

Any codes?Is the engine actually missfiring or is there just vibration?
