Hi,when At A Stop Sign Or At A Red Light My Idle Drops To About 250 Rpm(o2 Sensor?)...but I Don't Have A Problem When Driving...everything Seemed Right, Until I Would Stop...any Ideas Would Be Grateful....

Peace

I need to know what type of engine, and if it's manual, or automatic transmission... also the make and year.... get back to me and i will have your answer

I have a similar issue, however my 88 Jeep 2.5L TBI Cherokee idles rough when the A/C kicks in and slowly recovers. It seems that a switch/solenoid keeps clicking near the passenger side, but I don't know what it is, and the A/C clutch engages and disengages quite often. Any thoughts? As for when I came to a stop and had a low/rough idle, my EGR needed to be replaced - stuck open from what I could tell - idles smooth as long as A/C is off.
