Help! My 2000 AWD Astro thinks she's a mustang. Without provocation, she jumps idle to what feels like 4000 rpm and will not kick out of that high idle mode. (The Astro has no tach--so this high idle sneaks up on me!) This is the 3rd AWD Astro I've owned, but none has harassed me so. Vacuum hoses have been replaced--a new "intake unit/sensor?" installed ($157 just for the part, remanufactured)--but high idle resurfaces without warning. Any one out there with LOTS of experience with this otherwise great 4.6 ltr workhorse motor? I'm online because the cost of chasing rainbows at the shop is killing me--and the high idle is wearing out the Astro's brakes and my desire to keep this pretty "Regency" conversion colt. Sorry, I don't know what codes have come up--but each has been neutralized one by one without solving the problem. What I do know is that I've spent $500+ with no healing for Astro or me. Please help before my brakes give out....Thanks. Jon Heddleston (Virginia)
