87 Ranger 2.9 Rough Idle/Hesitation

[Johnny.B]

Hello, everyone. I normally introduce myself in the appropriate forum but I am running into some issues I need resolved urgently.

I own a 1987 Ford Ranger XLT with the 2.9. When I start it cold it runs fine until it gets warmed up and to running temperature, then it will have a rough idle. When started back up when warm it will run very rough and hesitate on acceleration, but fix itself after a while leaving only the rough idle. As of today I was hoping to hold it off until it finally warms up outside but today it's obvious it can't wait any longer with it getting worse.

Things I have replaced:

Spark Plugs/wires
Distributor cap & rotor
Spark Plugs
Air filter

I anxiously await any replies. Thank you.

Just saw this and I am having the exact same problem. Did you ever figure it out?

He was last seen on here February 9th of 2015. If he found a solution, he won't be coming back to tell us.

I would imagine he would get an email about. Thanks
