While out of town, a friend delivered my `88 renix blessed xj to my son so he would have a vehicle to drive while home on leave from his 2nd tour in Iraq. His Blazer was being eqpt. with a 383 stroker. Anyway. My friend got to experience my off and on, 2700 rpm idle. As the xj was idling high, he shut the ignition switch off. Just before it died, he turned the key back to the on position. This dropped the idle down to around 750 rpm's and it ran fine. But as most high idle issues go it was a short lived fix. Any ideas as to what would trigger the idle drop? A brief history of other temporary fixes: New TPS, IAC and Map sensors also replaced the ECU and tightened the exhaust and intake bolts.
