Hey, so in my 1992 4.0L Ranger with 103k miles. It idles very weird sometimes. Mostly when I start up after the engine is hot. Like if I cut it off after driving for a bit, then go in to the store for 10 minutes or so. Has no problem starting but it only reaches about 1500 RPM when it usually reaches about 2500. But then it drops to about 500 RPM after its ignited. I have to rev it up to keep it running. If i put it in reverse it sounds like its going to stall on me. I have done the plugs and wires, a transmission flush at about 99k, ive cleaned the IAC valve and put a new gasket on. I unplugged the TPS, and MAF for a little while and plugged them back in. Nothing has worked yet... I will be doing the fuel filter and a radiator flush very soon. I took it to a shop and they plugged it in to the old computer, and he checked all my vacuum hoses. Nothing came up.
Any ideas what else could be causing this or any tests I could do?
Could it be the fuel filter?
Anything with the EGR system or intake?
Anything willl help! Thanks guys!
