As I had announced in a thread on here a few months ago, I recently purchased a used 1993 Ford F350 SRW with the International 7.3 IDI diesel engine. I love the truck. It's not all that powerful, but it meets my needs nicely.
Anyway, after owning the truck for a few weeks, I noticed that some repairs were needed. The truck has 260k miles, so this is to be expected. First, the water pump had to be replaced because you could rock the fan back and forth with your hand. No biggie.
Next, I noticed that the injectors were leaking diesel fuel. After doing some reasearch, I found this to be somewhat of a common problem with the older 7.3's. I figure it has something to do with the introduction of the ULSD fuel. So, I ordered some remanufactured injectors from Diesel Care. I wanted to get new injectors, but they were on back order until the end of the year. So, I settled on the remans.
Replacing the injectors wasn't that hard of a job. But we did run into a problem when the reman injectors would not screw into its hole. We tried 3 different reman injectors, and ended up having to put one of the old injectors in it.
Anyway, the new injectors stopped the leaking problem. That's good. But now I've noticed a somewhat significant performance decline. When pulling a hill, unloaded, the truck just bogs down. For example, there are a couple of long and somewhat steep hills on my drive to work. Before, I could downshift into 4th gear and pull the hills with no problem...and even accelerate up the hill if I wanted. But now, when I hit the hills, the truck bogs down to about 1500 rpm in 4th gear and will not accelerate at all. I held the accerator to the floor...nothing. Just putted along at 1500 rpm (about 40 MPH). Today, I decided to pull the hill in 3rd gear. Pretty much the same result...it accelerated to about 1500 rpm and wouldn't go any faster. I noticed that there was no black smoke coming out of the exhaust either.
Does anyone have a clue what's going on with my truck?:confused2:
