found a DEAL (at least to me) on a '99 extended cab, f-250, leather, power everything, short bed 4X4 w/ 127K on the clock


the only problem is it has a rough idle and doesn't have much power. i am thinking it might be the valve cover harness for the injectors as he had someone scan it and it showed 2 injectors misfiring on the passenger side. he believes it needs injectors. truck cranks right up, no coolant bubbles, no excessive blowby, there is a little oil leak from what looks like the pan gasket.

what do ya'll think it may be? i've had 2 friends w/ 7.3's that has had the valve cover harness come unplugged (one had it happen twice on his). one friend told me it could be the cam position sensor.

what are my options on things to check? i should have the truck home tomorrow evening so i'm gonna pull the passenger side valve cover first and see what is in there.....

 

99 the major valve cover issue was corrected. The 94-97 with the two plugs burned the connectors and then made it sound horrible. Its not a CPS, the truck will either be dead and no start (no tach movement). Or you will be driving down the road and the truck will intermittently die... And then start back up, horrible feeling. Could be valve cover, but im thinking injectors more than likely. Still, I live the 7.3 and when you get your issues worked out you will too. Not the fastest truck, but very reliable. If it is injectors, get a good aftermarket set, they will wake the truck up!

 

the 2 friends that had this happen to theirs was in a 99 and a 2000 7.3 trucks, one was an f-250 and one was an f-350.... i knew about them burning up in the earlier years but what about just coming completely unplugged inside the valve cover? that is what theirs did....

 

so if it is the injectors what might cause these to just go bad? improper fuel filter change intervals? red fuel?

who makes either a stock replacement or a MILD upgrade that won't break the bank? i'm not wanting to make monstor power with this truck. it will either be a DD/ tow truck for my 96 Ram....

 

Never heard of them coming unplugged. The heui injectors go bad, not sure why (just like common rail ones do). Probably cause there are moving parts in them, not just pop nozzles. They arent as bad about blowing injectors on the 99+ p-strokes, but they do. There are many different manufactures of injectors, but as far as cost, RDS (Rosewood Diesel Shop) are far less than others I have found. I had a set of RDS Stage 2A in my 94, and OMG the difference. 334hp 657ft/lbs dyno with just intake and exhaust. It was like 1000 for a set of 8, you cant buy 8 stock ones for that.

 

The oil not being changed right might have something to do with the injectors going out too, since they are oil ran but that is just my $.02 one of those FS2500 oil filter jiggers help out the PS guys alot more than any other diesel

 

you can get stage1 full force injectors from tony wildman for $850, i would go ahead and have him burn you a chip for them also if you buy them.

It would be 1250 for a 99. Just going with that I liked my RDS injectors, but I was happy with my wildman chip, so I would trust him as well. You will love how much injectors wake up a stroker!

 

it was a night and day differance

...benjamin remember, you can always look back to the august issue of 8-lug at my tech artical on changing out the injectors
