Engine trouble

The past couple of times i've driven my 85 CJ7 I've gone to turn it off and taken the key out yet the engine is still "puttering"(it's running but not full out like it would with it turned on.). It's getting gas from somewhere. It sat there for about 20 seconds doing this before it finally turned off. Any body know what causes this or how to fix it?

Check the electronics on your carb. not sure exactly what is causing it but i believe there is some sort of device that cuts fuel when the key is off.. the drivers manual covers this Dieseling problem, i'll see if i can find out any more information for you when i get home tonight.

Sounds like it's "deiseling". Does it idle at a high RPM?

I'm with jeeprme1, a quick way to stop the deiseling is to shut the engine off while you let the clutch out a little or if auto shut the engine off in gear.

Get it fixed quick because it can cause damage to your engine.

Some causes can be carbon in the cylinders, timing, even a vacuum leak.

Sorry I can't be more specific.

Good Luck,
