Please help! Problems with first diesel
I bought a 2003 F350 CC dually. It has the 6.0, auto and 4wd. When I bought it, I got it for a pretty cheap price because the rear pinion had walked and broken some teeth. I figured with 130,xxx on the clock, it was worth buying and fixing.
I drove it for 15,xxx + trouble free miles. Recently, I was going from PA to RI to pick up a car. The dually drove great pulling my 20 foot trailer. I loaded the car, amd headed for home. About 2 hours from home, I had to stop to get fuel. I filled up and got back on the road. About 20 mins later, I started losing power. It kept getting worse and worse until finally, I was at my new top speed of 30 mph. I limped the truck home and chocked it up to bad fuel.
The next morning I went to look over the things I could. I am not familiar with diesels at all, so please be kind. I changed the air filter out since it looked pretty bad anyway. I changed the oil and filter. I changed both fuel filters and noticed that the filter under the truck looked like it was crushed inside the canister. I tried starting the truck and it would idle just fine but as soon as I would put it in reverse or drive, RPMs would drop and the truck couldn't get it's own weight moving. I thought maybe the Cat had collapsed so I cut the exhaust just before the cat and fired the engine up again. No change. The exhaust looked great, so I welded it back on. A local Ford mechanic told me the EGR valves are prone to caking and getting stuck, so I pulled the EGR out and cleaned it. Re-installed it and still no change. I recently removed the EGR all together and installed a spool. Still no change.
The truck is not putting any smoke out of the exhaust. I can barely get the RPMs over 2500. Like I said, it will start and idle like a champ. It just falls on it's face when I put it in any gear. If I let it run for 15-20 mins, I can drive it on the road, but there is a noticable lack of power.
I forgot to mention at the beginning, but as far as I can tell, there are NO mods on this thing anywhere.
Any and all help is GREATLY appreciated!
Thanks in advance,
