Scotty, First off I dislike coming to ask you or this community for help on this. Why? Here's the facts: all the information out there and I cant find what I am looking for. I have a 95 F350 with 5.8L. Friday I left work, truck ran fine for 600 feet. Yes short distance. sitting at red light. started to go and I had major hesitation but she was moving. No stalling. check engine light..... i cant say it was flashing for it was so irregular. solid for a second, then off 2, then flashes, then off. then solid. acceleration poor. I got to 25MPH in 1/4 mile. I did a neutral coast and restart. I had acceleration back but solid check engine light. turn on my side street a 1/4 mile later and again slow acceleration. truck accelerated to 30 mph till i turn onto my main street. acceleration still the same. Throttle wide open motor sounds dead, no power. but the motor never stalls. partial throttle acceleration is slow.

Now The biggest issue. DID I LOSE MY ECM? I tried reading my codes and I get nothing. tried "KOEO" and "KOER". I tried both test light and dash light (check eng), no flashes. Light stay solid. I check my connections of jumpers with truck off everything is neutral except the test light port which goes "open" with key off.

I don't know if you need past history on this truck, just know I did read a code before. it was in relation to the throttle body. it erased when I did a tune up.

Thank you, But this truck is OBD1. That is why i am using jumpers instead of scan tool
