So I got in my jeep tonight and my check engine light was on. If I let it idle for too long the rpms would go too low and it would stall. Also once driving the rpms go all over the place revving high and then dropping. I have a slight hesitation in the throttle too so when I give gas it hesitates. Im assuming I have a vaccum leak but does anyone have any input on fi.ding the leak or problem?

 

As always, several things can cause your symptoms. HOWEVER!!
Your Jeep is trying to tell you something, by means of showing a check engine light. That is usually a good start in the trouble shooting. Use that. Have the codes checked (assuming you don't have a code reader) and bring those back here. We can take it from there.

 

I actually have a code reader so I'm going to see what its throwing but ill check that tomorrow
