Question about 1989 Ford Ranger
Ive been having problems with my truck for a while. Sometimes it idles rough and I loose my rpm`s often when I am driving. So I hooked a computer up and it says something is wrong with my EGR. I took the EGR valve off, cleaned it, put it back on, tested it and it passed. But the computer says I still have a problem with the EGR. So I decided to replace the EGR vaccuum selanoid and it dint help at all. The EGR valve works and so dose the EGR vaccuum selanoid. What else could it be?
I would still try to change your egr!!! sometimes egr test good but still they can stick open and that can cause idle problems so if you want to get your prob fix change egr valve
take that egr off and put in a new one !!!!
Have a great day

Your problem sounds like it is the egr position sensor.
Depending on engine it on top the egr valve or a pfe sensor on the egr tube.
