Idle stuck on 2000 RPMS

mfreeway · 05-19-2008, 01:56 PM

Two days ago I was getting off the freeway. I was down shifting but the RPMS weren't being lowered.
I was on the main drag, I ran a red light, almost ran a kid over until I finally home. The RPMS were as high as 3000 but settled in at 2000.
I checked the 2 cables, accelertor, and cruise control. They look fine. I did find 1 vaccuum hose that was hanging in the drivers side firewall manifold. I'm not sure if it is a vaccuum line because it appears to have a sparkplug type filament inside. I also found a hose dangling from the passenger side 3 way manifold. It smells like fuel. I have very bad eye site.
My car is a 1994 5.0 GT. PLEASE HELP!!

I racked my brains out on this one. I asked the same question several months ago on this forum, most reply's were steering towards the TPI but try as I may I could not get the car to respond. I finally went to a local mechanic I trust, he has all the Snap On equipment and the knowledge to use it and told me it is the CPU, that's right the cars computer.
I found a site online goecm.com and called them, the guy was very helpful and knowledgeable.
p.s. you might want a local mechanic to check yours out and verify this, my car is still laid up as I have not ordered the CPU thanks to the present economy.
