Hey my jeep is cutting off every time i stop unless i keep giving it gas and sometime ill hear a grinding noise and it slows down as i slow down but when i give it gas it stops. Does any one have a clue what this can be?

 

it probably needs an idle air control valve

also the cat housing on my jeep sometime rattles at low RPMs. maybe that's the noise youre hearing...?

 

I work at a jeep dealership and my buddy who works with me has a jeep and he had a rattling noise. It was the shield around his cat.

 

its either the shield or the cat is broken/clogged up. both are EXTREMELY common on a jeep.

 

See the thing is that i just got a lift on it about a month ago and the grinding sound seems like its coming from my trany. i know i need to work on my idle but i thought it was a spring ill check the air valve. I gave it my first ever tune up and i changed the distrbuter cap and all the spark plugs and wires can that have anything to do with it?
