Engine/Transmission (1998.5 - 2002) Loss of Power..........

[CumminsPuller]

I left out for Dothan, AL Friday afternoon with my 8,000lb GN and a 7,000lb DC motor on it. The drive over was great. With the DD1's installed and the DTT transmission it runs great. Gained approx. 2 MPG. EGT's pre-turbo never exceeded 1100. After reaching my destination, dropped off the motor and headed back. Power seemed down a bit. After fueling up at exit 54 on I-65 South I get going again. First hill I come to I get on the go pedal a bit to maintain speed up the hill, seemed I had to get in it a bit more. About half way up the hill, without warning the truck just came alive and took off like a rocket. It was Like there was some sort of restriction somewhere. I really I have no idea what this could be attributed to. Any ideas would be appreciated.

What was your fuel pressure at this time?



What is the condition of your fuel filter?

My last fuel filter change was at 197,000 miles. I change it every 5,000. I checked my fuel pressure before I left for the trip and I was running just shy of 11psi at idle pre and post. As far as cruising and WOT, I did not check that. And I have not checked pressures since getting home yesterday. The trip was about 1200 miles round trip.

Blame it on electrical

I've had that happen to me twice now. Last time I was changing from 2X3 to 3X5 and when I punched it, nothing. The rpms just sat there.

Now here's what makes me believe it to be electrical. When that happen I tried to return to 2X3, no responce. I couldn't turn the UFM off or up or down. The lights just stayed at the setting the problem occured at.

I turned off the key, started back up and everything works fine. I know your running the EZ but it might be an avenue to explore. Goodluck.

LoneRam........

Are you possible suggesting maybe the 2 year old EZ might be slowly dying?
