ranger revving problems?
Hey yall my dad has 98 Ranger with the 4cyl (i think its 2.3?) 5 sp, my question is when he's driving it (especially when he takes his foot of the gas and pushes in clutch to slow down, dont know if that has anything to with it though) it will start revving up but when he comes to a dead stop the engine will go back to idle. I thought it may have something to do with the throttle linkage sticking so i sprayed it with wd40, then i did it again with brake cleaner, and it seemed to stop for about a week, then it started again and we tried it again but this time it didn't work. Does anyone know what this could be? Could this be some sort of problem with the throttle linkage or maybe some sort of vaccum issue, ive also heard of the IAC's being a common problem on F150s, could this possibly be the IAC going bad? Any ideas or tips are greatly appreciated. Thanks guys.

IACV Probability
Howdy, countryboy116,
After pulling the computer codes:
You may not know it but the IAC / IACV - Idle Air Control Valve is a possible cause of your situation.
My son had the same problem in his Ford wagon, replaced it & it was the culpret.
And on my Ranger, about 5 years ago, I took it off & cleaned it but don't exactally remember the procedurements.
I am going to research this further today 7 will be back w/ more info.

Thanks for the response, i was reading through here some, im not usually in this section of the forum (i have a 97 F150 and dad has another 04 F150 so im more up on the fullsizes) but it seems like that may be it, thats kinda what i was thinking. Thanks again

Iacv
Hi countryboy116,
As I said I will be back today:
After further research I have found that the IACV may not have to be replaced but can be cleaned out, after removal, w/ carbureator or a decarbonizing cleaner.

Good Luck to all!

Thanks for the reply, we went ahead and got a new one and i put it in today, hopefully that will do the trick, looked through some stuff and that sounded like the culprit. Thanks for your help

A Thank You
hi countryboy116,
Glad to be of assistance.
I too did research on this & still feel this was the problem.
We are all here @ FTE, to help each other in time of need.
Oh Yeah! While you in there check around the inside of the intake it may need a cleaning out.
