HELP!
Towing a very heavy trencher (14klbs or so) out of Phoenix, AZ on I-10. Slow going coming up the hills and EGT's in in the 1,000* range down in 3rd gear. My truck is a 94, 5 speed, long-bed crew with a 4.10 gear. It has runn very well for the 4 months I've owned it and I've put about 5k miles on her. It indicates 198k miles though with the speedo acting goofy, bouncing around between 10 and 85 MPH at a steady 75 on the GPS, it doesn't count the miles properly. Could be up to probably 240k - 250k on it.
Nearing the top of a fairly long hill, the truck suddenly lost power like somebody flipped a switch and killed half the cylinders when under power but it would idle normally. Barely nursed it into a brake check station. It took about a 1/2 hour for the EGT gauge to come down under 300 deg at an idle. Another hour sitting and cooling then we were off again. Ran like a champ.
Decided that possibly the Tow Tune from the Edge Tuner should be set back to stock in an effort to control the EGT issue so we planned to stop at the very next rest area. As soon as we hit the off-ramp for the rest area, the shuddering and severe loss of power reappeared. This time I looked at the Boost gauge and saw zero boost though I had my foot in it pretty hard.
By the time the tow truck got to us, my truck has barely enough power to get it on the trailer to bring it home.
Some of the issues I've been told it may be are:
O-rings on the injectors leaking pressure away on the HP oil system when the oil is thin and hot requiring new o-rings/injectors
Bad CPS though it does not seem to have the classic symptoms of that issue
Overall bad HP oil system pressure, likely to due to o-rings and worn HPOP.
I've also been told the injector replacement is a huge pain in the butt, the injectors are terribly expensive ($300 each or so?) also requiring replacement of the glow plug/injector harnesses plus associated gaskets etc, totaling around $2,400 in parts alone.
The guy that gave me most of this info also said I'd be better off swapping to a newer version of the 7.3 as many mods have been made at the factory to resolve many issues the early models had. If the swap actually IS a good idea, anything like computer, wiring, other issues I should know about before I rip into this thing?
Or should I just go get a pack of matches to go with the 5 gallons of gasoline I've had my eye on? :dunno:
How much did it suck that I had to buy another truck to pull my Ford home, and that other truck was a Chevy? :tase:
