My father has an 02 F350 6 speed that has been running great until this morning. He left the house and then all of a sudden there was no acceleration. The fastest he could get it up to was 30mph. During all this time, there was no smoke. He only has 60+k miles and has had no issues until now. He did say that he moved the wiring harness under the turbo and the rpm went up but when he got back into the cab it went back down. He has removed and reinstalled all the connections he could get to but no good. The check engine light is on and he plans to get the code this afternoon but until then, if there are any ideas, I would appreciate hearing them.

Thanks
Scott

For those that run into this issue, check the wiring harness connection for the injectors at the valve covers. We had to pull the passenger valve cover to reconnect the harness. While we had it apart we used some wire ties to prevent it from happening again. Runs the way it is suppose to!!
