Hello All. I have a problem with my 94 YJ with the 2.5L that has me baffled! The problem is that it idles anywhere from 1600 RPM – 2600 RPM. Here is a list of the components that I have changed so far: AIS Motor, Throttle Positioning Sensor, Oxygen Sensor, Distributor cap, Rotor, Plugs, Plug wires. I have also removed the Throttle Body and cleaned it thoroughly. It now runs very very well but still idles way too fast. I have also checked for Vacuum leaks but can’t find any. Throttle linkage is working fine also. Does anyone have any suggestions?? Thanks much! John
