#1 of 4 1995 Ford E-350 7.3 Diesel Bogging Problem by flattracker12m Mar 12, 2009 (8:08 pm)
Hello, I have a 1995 E-350 7.3 Diesel. For about a year now and 30k miles, I have had a bogging problem from time to time (sometimes every hundred miles, ten miles, or 2k miles). The thing will be running great down the highway and all of a sudden it will start loosing power until you can't go even 40mph. When this happens, you pull over, shut off the truck, start it, and it runs great. Sometimes you have to do this a few times before it kicks in. Every once in a while if you drive it long enough and baby it , the truck kicks back in up to normal power. Before having this problem, I did have a new transmission installed. I have had it into the shop where they have replaced a Cam Positioning sensor as well as in intake sensor. It seems like the problem is getting worse and is happening more frequently. Any help? Thanks, Brady flattracke12myahoo.com Replies to this message: edford (Apr 01, 2009 11:01 pm)

Replying to: flattracker12m (Mar 12, 2009 8:08 pm) I have a e350 too with the 7.3 turbo diesel powerstroke engine.. I had similar probs as your 1. Try replacing the IDM module. Its a little box on the right fender near the air brake assy..that is the module that controls the the injectors. 2. The powerstroke engines has its own hi pressure oil reservoir that builds up hi pressures to open the injectors.. over the years the oil tends to sip away.. The hi pressure oil reservoir is located front top section of the engine just beside the aircon compressor. remove the airfilter casing and unscrew the pressure switch on the left side rectagular oil reservior. There is a filler plug on the right but it is quite inaccessible. check if there is oil, if not fill it with oil 40 and reverse the procedure then start the engine. eddie

The ford mechanics may not know this trick because the engine was made by NavStar.. I had mine brought to FORD repair shop and it took 10 months to get it back.. in the end I was the one who diagnosed the problem cause I bought a manual and have to teach the stu__d mechanic to fill it with oil..He taught the oil will be coming from the main sump but the manual says its separated/ independent....hope the problem/ case is the same as yours. eddie
