Hi guys! I am new to this forum and Troopers. I just purchased my first one this afternoon and I have already began wrenching on her.

Once I start the truck, it stumbles between 0 and 1000 rpm, and usually dies if I don't give it gas. However, after I start going, the idle levels out to 1100 at stop lights and stops, perfectly. But if I were to shut it off and start it again, it stumbles and repeats the described issue (regardless of temperature).

I was thinking it was a vacuum leak but I wouldn't know where to begin. Any help would be greatly appreciated!

1990 Isuzu Trooper 4x4 2.6 SOHC

Random information: I found a cracked vacuum hose from the air manifold to the turbo. I'll be replacing that tomorrow. I also have a hole in the muffler, again, random.

Thanks!

Tom
