I just put in a 2" lift in my 99 xj and now it starts pretty rough. I had to add some throttle today to get it started and had to keep the engine revved to keep it going. This all started right after I put in the lift. Any ideas?

 

It's prolly just a coincidence that your engine trouble started after u put on you lift

 

I knocked off a vacuum line when I was tightening the shocks up. Ran pretty much the same but threw a CEL. Check your vacuum lines and listen for leaks.

 

mine does this from time to time.

 

Does it happen alot?

Mine seems to be idling a little rough too.
