gonna need more information than that. Does it stall at idle? Is it stalling out while your driving? How long is it running before it stalls? Engine up to temp? Check engine light? What codes are you getting? Did you mow your grass that day? What does it idle at? stock motor? Fill out your profile so we can better help you out.

Based on the lack of info this may not apply... but my last Jeep had a carburetor and it behaved the same way - it was a vacuum issue. It was fine when going at a steady pace but at every light it would stall out.

No it does not stall at idle. I can turn it on and it keeps running. As soon as I start driving it stalls out. If i put my foot on the clutch and the RPMs go down it will just stall. I have to keep my foot on the gas when I pull up to a stop sign or something. It will stall out at idle after driving. Engine is up to temp. No CEL. Yes stock motor.

Thanks!

I had a similar problem a month ago and it turned out that i had a rusted distributer cap terminal and wire. I replaced them both and have not had problem since.
