Cruise control sometimes doesn't work, especially first trip of the day. Stop, shut it off and restart, then it will usually work. I just figured out that if the cruise isn't working, neither is the vg of the vgt (no codes). I use to be able to slip it into neutral while rolling (automatic)...

2003 excursion turned switch to 4hi today and nothing. no 4x4, no dash light. I did some research and found half a dozen related fuses that all tested good. Two things I noticed: 1.) The dash light does not come on like normal when all the others do at start-up. I think they call that...

I suspected a charge air leak, so I pressure checked the i.c and pipes by plugging the hot side by the turbo and cold side at the intake horn. No leak. Then I watched video of guy plugging one side only (intake to turbo), and thought the other end could leak through the engine??? I tried it...

My glow plug controller failed. When trying to start without glow plugs, I noticed exhaust coming from exhaust manifold gasket around cylinder 8. I was thinking of pulling just those two bolts and slipping in a new gasket and re-torqueing around just that one port. thoughts? ...And yes, I...

Merry Christmas!! Had injector 7 go bad. failed buzz test. I cleaned the spool valve and replaced the coils from another injector I replaced that had a cracked tip, and reinstalled. Had much better (but not full) power, less vibration, but still failed power balance (cylinder 7 contribution)...

I have a very low mileage injector from Ford with a cracked tip. Is it worth more than the $180 core?

Nearly a year ago, I was experiencing low power and fuel smoke and diagnosed a leaking injector o-ring. Since the 03 was new to me with 260k miles and a family road trip in the near future, I replaced all 8 injectors. A couple other injectors I pulled were burnt on the bottom, so I did some...

I recently replaced my injector sleeves and all 8 injectors with new stock injectors from Ford. During our 1400 mile family trip to Snowbird Utah (from Minnesota), I started noticing a vibration more and more and power seemed to be a little flat. On day two, at first start up, an injector...

I bought a new hfcm because the drain plug was seized and destroyed trying to remove it. The new hfcm has only two electrical connections and not the three my old one had. Did I get the wrong hcfm? I think the last connector was for the fuel heater. What should I do? I think I need...

Is there any need to change fuel filters if I have plenty of fuel pressure (even under full load) if I have a gauge to constantly monitor it?

03 excursion 260k miles. Massive white (burn your eyes) diesel smoke (not antifreeze) all the time (proportional to throttle). Happened quite suddenly with small lack of power. Starts and idles and runs quiet and smooth. No codes. Passes koeo and koer tests. Injector buzz sounds perfect...

Looking for part numbers for rear ac lines / auxiliary a/c lines. Previous owner deleted the rear air and I want to resurrect. I'm assuming the lines leaked.

I just changed the oil on my new to me excursion. I thought I had the factory cap because it is not the tall one, looks like the Ford one and has the NM torque spec stamped into it. The new filter instructions say 25 NM and everything I found online says 25 NM... but my cap is stamped 40 NM...

For my new to me Excursion, I bought a rebuild kit for my turbo before removing it. After removal, I see it is too late and needs to be replaced. To avoid this in the future, I am thinking of just doing a scheduled rebuild every so may miles. What do you recommend?

I am getting ready to do my bulletproofing. If my head gaskets can be confirmed to be not currently leaking, I will be installing studs one at a time. Right or wrong, this IS what I will be doing and have no interest in debating this. Recently, I noticed my coolant was down about half an inch...

Any scientific reasoning out there as to why or why not install used ARP head studs? Does anyone know if they will permanently stretch before they snap?

So I read that the vgt is pulse width modulated. Is this correct? Default position with the actuator unplugged is vanes open. (would be a dog on the bottom end). Is this correct? If you applied a constant 12 volts for 10 seconds or so at idle, would the vanes fully close?

Does tow/haul modify the regular program or is it it's own program. In other words, If I get a custom tune will the tow/haul modify that new program?

My new to me 03 excursion which is supposedly the same as a 250 has a dana 50. Other than the wheel bolt pattern, is there any downfall to putting in a dana 60 out of an obs (that I already own)?

I went to sign the papers and pick-up our new 03 6.0 excursion from the dealer tonight. between the time they started it and drove it up front, the "check gages" light came on and the gage had no oil pressure. (It had been fine during my five test drives.) I know there must be oil pressure or...
