Go figure!

 

I think this is the one I get when I forget to push in the clutch during koeo test. If your auto trans is in neutral, I think you'll get it also. candyspaw

 

I got an Innova code reader for Ford OBD1 that spells out the code instead of flashing. All that counting gives me a headache. Get the extension cord and you can do your tests in the drivers seat. Got it on Amazon. candyspaw

 

I had this and one thing I found was sticky injectors and another was a defective engine temperature sensor. I also found that my ignition coil was internally shorting to ground. The truck would stumble when it rained, but I couldn't see arcing under he hood in the dark. Went away with a new coil.
