My 5 speed Ranger has been showing intermittent check engine signals - they go away, then return, sometimes after a couple hundred miles, sometimes after just a few miles. I need to pass a smog test to re-regiister, and the light would not go away- the code on my scanner was for excessive idle...

The truck is a '98 XLT with the 2.5l 4cyl, manual. When driving (hot or cold, highway or in town, 25ft or 200 miles) the engine speed stays high, or goes higher, when depressing the clutch. It will stay there, no matter what, never come down, until the truck comes to a dead stop. I've coasted...

First time posting here but I've been reading all the posts on here as well as other sites trying to solve my high idle. I'm running out of posts to read so I figured I'd try posting it and see if anyone has any more tips. It idles at 1200/1300 rpm. Its a 1991 Ranger 4.0 OHV Auto 4x4 STX reg...

I have a 94 Ranger with the 3.0 V6, when I start it cold the idle will rise and fall like mad, I tried taking the IAC off and cleaning it, the next day when i started it the truck seemed to idle ok, then it dropped to where it almost died, but then it sat there and idled for awhile just really...

Hey everybody, really been enjoying reading all the information here. I bought a lovely 2001 3.0L XLT with flare sides about a year ago and our relationship has been on the rocks for the past few weeks. I'm getting conflicting signals and not sure really what's going on. I'm having rough...

I have a 1996 2.3L. I was originally pulling codes for Insufficent EGR flow as well as Ignition Circuit 1 & 2. After putting in close to $1000 into this truck I am currently pulling P1506 Idle Air Control Overspeed. The truck is no longer pulling the previous codes (EGR & Ignition). The truck...
