Newbie! First Diesel, Need Advice!
OK, here goes. This is my first post and I need some advice. Iíll try not to make it too long.
I just bought my first diesel, 95 F250 Ext Cab 4x4 7.3L, E4OD, 4:10 gears, 207000 miles.
Owner said it sat for last 3 years, drove maybe 10 miles a month.
My problem is it sounds like it has too much rattle in the engine especially after shifting to 2nd & 3rd. Seems to have plenty of power but not a lot of get up and go. I drove a 96 and it had a lot more pep when shifting.
Oil pressure gage reads steady between the o and the r in NORMAL, which is less than midway. Starts good. Doesnít seem to miss or hesitate. Just sluggish and a lot of rattle. I was told 95s were like that.
Had local truck shop run a scan on it and they said it has 5 cylinders low on contribution test.
My question is, should I just replace all the injectors and if so, maybe upgrade them and to what size?
Or, hereís what Iím thinking: since it sat for so long, replace all filters and fluids, check hpop pressure, do the fuel pressure regulator shim mod, intake 46637 mod, ebpv delete, 3Ē down pipe, and muffler delete and then have it scanned again.
If the injectors are bad will doing these mods put my engine at risk for more damage?
Also, the mileage sucks. Havenít got specifics yet but probably between 10 and 12 mpg. Also has very slow fuel leak on top of engine.
I am going to use this truck as daily driver and occasionally to pull 28í 5th wheel and 18í boat singly and in tandem. My main objective is mileage.
Am I thinking right or should I start with the injectors first? Or would sitting for 3 years even cause any of these problems?
Iíve been reading these forums and you guys seem to have been through it all so any advice would be greatly appreciated. Sorry so long but Iím not sure where to start.
