1991 Ranger Hesitating and Stuttering
It's hesitating and stuttering in a sort of random pattern. It can be rogh getting up any sort of hill. Yesterday I had to stop on a hill and didn't think I was going to get it to move.
I took it to the local AutoZone to get a code dump and they would not do it. "It's to old we only do this for ODB2." This is the same place that told me you don't need a code reader we can do that for you. So the first time I ask ....
After a lot of goggling and reading (lots of it here) I figured out how to dump the codes and found a list. Got the codes out in spite of some incorrect instructions. I used the jumper/blinking light method.
18 Ignition Diagnostic Monitor (IDM) failure
28 loss of primary tach right side
33 throttle position sensor noisy/harsh online
88 electro drive circuit fan circuit failure
After some study I think 18 and 33 are my main issues so I'm planning to replace these.
Any thoughts on the others.
