96 2.3 ranger rough idle goes away?
i bought this ranger about a month ago and everything i have done still dont fix the prob, it will idle fine then about 5mins or so the idle drops and misses and runs rough but if i hit the gas it dont have a miss at all and runs smooth until i let off the gas again. Ive changed spark plugs, wires idle air control sensor, what next the egr? there is no vacume leaks either i already checked im just stomped by what it could be.

Re: 96 2.3 ranger rough idle goes away?
check the IAC valve (idle air control)
it may be stuck....try taking it off and spraying it down with some carb cleaner

Re: 96 2.3 ranger rough idle goes away?
When you say you changed the idle air control sensor you mean the idle air control valve, it is attached to the TB. a few long shot thoughts. did you pull the neg cable for 20 minutes to let the pcm reboot? super long shot, how is the fuel filter/(should be replaced anyways). air filter?................and i agree with cleaning the maf(only use maf cleaner , do not touch the wire, do the pcm reboot after this)
also i have a cheap Costco code reader $20, when i have an issue like this i check for codes when the truck is acting up. A lot of time the code is pending and then goes away without throwing the cel

Re: 96 2.3 ranger rough idle goes away?
Try the fuel filter... I had the same problem with mine and replaced the fuel filter and it works perfect! Do it yourself though because ford tried to charge me 300 dollars to get it done.

Re: 96 2.3 ranger rough idle goes away?
I guess I will just keep repeating myself and then youdo what you want. I would replacethe Fuel filter. Check the air filter, clean the maf and reboot the pcm. I also would get a codereader and randomly check for pending codes.

Re: 96 2.3 ranger rough idle goes away?
i replaced the air filter when i did the tune up and just cleaned the maf the only thing left is the fuel filter but before i do that heres something to think about. When i disconect the front coil pack it runs rough when i disconect the back it just drops idle alittle bit nothing too bad so could it be the back coil pack ? im goin to replace the fuel filter now.

Re: 96 2.3 ranger rough idle goes away?
Seems I am having the same issue. The voltage seems to be low on the indicator and it idles rough from time to time. Dies on idle when first starting up. Once it gets warm it idels without dying, but it will idle rough. 98 2.5 liter
