I just had my 2.5 rebuilt, but now I am having idle problems. Sometimes it idles great and sometimes its ruff and the tach goes to zero, also if its hard to start then you can bet it will be idling on zero, if it starts right up, then the idle will be on about 800-900. Any suggestions, thanks

Check your sensors to make sure they are all connected properly and no vacuum leaks.

I have checked vacum lines, trying to find the ISC sensor on this thing

I’m having the same problem with mine, 1994 YJ 2.5. Did you ever get the problem fixed or diagnosed? Thanks! Matt
