XJ Weird Idle
I have a 99 Cherokee with the 4.0 and when It warms up a bit after wheeling, slow driving, etc it kicks up the idle to about 2000. Now recently once in a while sitting at a stop light or slowing down the rpms will drop to 500 or lower (scared the ***** out of me when it first happened). Planning on checking all the vacuum lines and clean the tps tomorrow. Any ideas?
