    Well - bad news Fixxxer - last night must have been a fluke. It ran like before today and got so bad that I barely got it home. Sometimes it wouldn't accelerate past 20MPH.

    I am back to thinking it is the pedal. Some pedal points there seems to be NO response, and then all of a sudden a little response, etc.....

    Was the sensor disconnected the entire time?

    I am wondering if i was accurate in stating that you could leave it disconnected for that long of time. I have never actually left one undone fo that long of time. I could not find a reason for it to matter though. if the symptoms went away when you at first unplugged it i would still replace it. plug it back in for a day then unplug it again and see what happens.

    I also had the valve cover gasket go bad that caused one injector not to work making it run like sh**, also barley making it back home. This was an intermittent issue some times running good sometimes not so good. codes came up #4 injector bad. Inspected gasket and could see burnt wires. Wires for glow plugs and injectors are molded into the gasket.

    I thought when icp goes bad computer runs on default mode.

    Alright - new update. Ran it this morning with the ICP unplugged; ran like crap. Did the pedal/cruise control trick - still ran like crap.

    Plugged the ICP sensor back in, and it ran like it did a few days ago which was just some mild hesitation.

    What does everyone think - should I start by replacing that sensor?

    It seems to be your problem cause by symptom. Do you have access to a scanner with a datastream so we can accurately check for bias. I am wanting to see the icp pressure and voltage data.

    I have access to a OBDII scanner, but I don't believe it can stream data.

    BUT - there was a brand new ICP on ebay with an hour left with free shipping for $100 bucks so I bought it. If it doesn't fix the problem, I am only out $100 bucks. I am not one to just throw parts at it until I stumble on the right one but I don't feel horrible replacing a sensor that might go bad on me anyways....

    They go bad all of the time in my line of work (but i fix them every day) give it a shot. disconnect the batteries overnight to clear the keep alive data and let me know what happens.

    Will Do - Thanks. Like I said - for 100 bucks, I'll just consider it preventative maintenance if it doesn't cure the problem...

    Replaced it today, put about 100 miles on it with no problems.

    The old sensor had oil in it.....

    None in the sensor.

    The sensor is in the high pressure oil stream. so there will be oil on the backside of the sensor (the port with the threads). I messed with a truck here yesterday and disconnected the sensor. The truck starts to learn from no input after so long and started acting funny. So as far as diagnosis goes the sensor can only be disconnected for a few minutes until the truck starts to adapt to no input and act accordingly.

    I am glad you got it fixed. at a dealer you would have been looking at a hour diag and hour to replace the sensor and re-test. Also i beleive that sensor is over $200.

    Glad you found your problem cause!

    I don't go to the dealer after they tried to charge me $675 to replace the front cable on my Parking Brake.

    Thanks again for your help here!!!!

    Hello Fixxxer22, I recently bought a 2000 E350 van with a 7.3PSD and it ran beautifully when I test drove it. Shortly after I bought it I started to get a hesitation under part throttle. When it starts the chugging it also smokes out the tailpipe ( white/blueish smoke) and you get an overwhelming smell of diesel in the van. It will run ok under a very light throttle and the chugging goes away when you put the pedal to the floor. The turbo spools and it takes off like a rocket. I had the dogbox off the other day and noticed when the motor starts smoking and chugging you can see smoke puffing out of the connection where the drivers side up tube goes into the turbo Y tube. My problem sounded like the one described in this thread except for the no smoke symptom.
    Any help you can give I would really appreciate it. Thanks.
