Man, when its cool mine runs great. But when the temps are up I notice some power loss especially if I am towing something.

NEED HELP!

Mine would suddenly lose power then kick in again. Had it happen twice on the road to Payson on steep hills and that is dangerous. I know they had a number of problems with the EGR systems during the '03 snf '04 models. When the cooler blows you will see white smoke pouring out and water dumping out of the tailpipe. Hope it isn't that.

It does kick in and out. But really bad tow when like going to Roosevelt up the beeline. No white smoke but I thought I had cooler blow and 2 injectors about 2 years ago. Ford is telling me it is the EGR valve, not cooler. Does that make scence?

YES I DOES MAKE SENCE THAT IT COULD BE THE EGR VALVE, NEWER DIESELS BEING COMPUTER CONTROLLED HAVE KNOCK SENSORS AND THE EGR NOT OPENING AS PRESCRIBED BY THE LOAD THE COMUTER IS SENSING WILL CUASE CYLINDER TEMPS TO RISE AND ENGINE WILL START TO KNOCK, THUS THE KNOCK SENSORS WILL SEND SIGNAL TO COMPUTER TELLING IT TO BACK THE TIMING OFF TO STOP THE PINGING OR KNOCK--THUS LOSS OF POWER DUE TO TIMING BEING RETARTED TO STOP THE PINGING, DOES THAT MAKE SENCE?

take you intake air temp sensor and run it in to the ac in the cab you will feel a good gain and fix your problem you can wire it so you have 2 sensors and unplug your stock one just have to buy an extra sensor the colder that sensor it the more fuel the comp will send
