Down on Power

I own a 02 F 250 7.3 L w/ over 150,000 miles on it. No real issue's up til now expect the occasional cam shaft sensor. Over the course of the last few mpnth's I have noticed the truck down shifting a lot on grades and generally seems to be down on power under normal driving conditions. When I ask it to perform, or get on it a bit the truck seems to have plenty of steam and really takes off. The truck gets regular routine maint. to include oil, air and fuel filters changed. Just looking for a little insight before heading to the shop. Thanks in advance.

Check your exhaust back pressure sensor / tube. Several people have noted having poor performance with this clogged.

Another Issue

Okay I took the sensor and line off just as instructed and man was it ever choked up. I cleaned everything up and attempted to put the line back on only to find that the nipple on the side of the engine is stripped. I got the line back on and everything is back together but the line is certainly not tight. I don't think it would back off but there's defiantly a little play in it. I took the truck out for a test drive and it did seem to have much better power. I guess my question is now do I try to get the get that nipple out and replace it, or leave well enough alone, atleast for now?

It needs to be air tight. If its leaking - fix it. Was there much gunk up in the sensor? If you can't get it all out - sometimes you have to replace it.

Sensor

I'm pretty certain I got both the sensor and the line cleaned. Just wondering how difficult it'll be getting that nipple out?

Another Question

What would happen if I just disconnect the plug to the sensor on top the motor and purchased the plug termination ends from dfuser?

Thanks

It might work. I'm sure its set up to just give a constant signal that's within normal range.

I was going to suggest something like that. I'm not sure if anyone has anything like this.

I wonder how many people have a clogged sensor and are actually feeling lack of power from the EBPV being closed? I don't have one but I guess its worth a try to clean out the line and sensor.
