2024 order banks will be opening in June sometime. Granger, Dan Cummins, Mark Dodge and Koons discount heavily if you order. Discounts are $11,000k to $12,000k off msrp, they’re all about the same. If you buy a TRX on the lot it’s usually msrp.
I would suggest having someone help with the rear leaf springs. I did it solo, it was quite an effort. Extra pair of hands is the way to go. On the fronts I went in small increments when compressing, make sure you keep the threads lubricated so the compressor doesn’t bind up.
Reinstalled stock port fuel injectors, reverted tunes back to stock. Today I dropped the truck off at the dealership to see what was wrong. They called me a few hours later with the most anticlimactic news of all. They couldn’t find anything wrong, took it for a drive, interstate, city...
Well, I celebrated to soon I guess. Truck just started having cylinder 6 misfires again. If I get on the truck while cruising it will vibrate excessively and throw a code, cylinder 6 misfire. All the obvious things have been checked multiple times, I’ve replaced spark plugs, ignition coils, cam...
VICTORY!!!!! Everything is back together, cleared the ECU, cleared the TCM, warmed the truck up, prayed and then did a hard pull. No issues, truck pulled hard.
Culprit: MAF Sensor on the firewall side of the the intake manifold. It hasn’t been looked at in 75k, it was covered in oil…dripping...
If that’s the case, I won’t be messing with the DI injectors, I’ll let Ford play with those.
Pulled the manifold, by chance I looked at the MAF sensor on the back of the manifold, it was dripping with oil. I pulled and cleaned all three. Not sure if this is the fix yet but it might explain why...
We’re going to check the port injectors, will swap 6 to 5 and I’ll check the resistance on all of them. If that doesn’t correct. I’ll baby the truck to where I can swap back to gas, then then put the original port injectors and stock tune, then take her to Ford.
Removing the swapping injectors was a next step considered, the problem is I’m running e85 and have half a tank, so I can’t just pull them unless I dump the tank completely and fill back up with gas immediately.
What I did just do was verify compression on cylinder 2, 150psi. So I threw the...
Update: used a cylinder compression tool to check the cylinder 1, it’s at 150psi. Is this correct?
What other options do I have before I take it to Ford? Is the gasket messed up on cylinder 1 which is why it’s leaking oil? Could that be why it’s nuked two spark plugs? Was there excessive...
Update: P0306 still firing when I accelerate hard, which is misfire cylinder 6. On a whim I decided to see what cylinder 1 spark plug looked like, brand new with less than 50 miles, see photo. Tip is absolutely melted off, oil covering the threads all the way up.
Using a flashlight to look down...
Swapped ignition coils, 6 to 3, hoping for the error to move to 3. It stayed at cylinder 6, again getting the P0306 miss fire error. If I do gentle driving with no hard accelerations, everything is fine. The vibrations and error code don’t come on until I do a hard acceleration with a downshift...
That was short lived, secondary ignition kicked in accelerating to get on the interstate, truck started jerking, check engine flashing. Pulled over and got the P0306 code, this after fresh plugs. Going to swap coil 6 to 5 and see if the miss fire follows. I was able to make it home with no...
Update, changed the plugs. Cylinder 1 plug was covered in oil and melted, shorting out the plug. After starting it, carbon colored fuel mixture shot out the passenger side tail pipe spraying the wall and a water fuel mixture was on the ground back my the bed were the exhaust pipes clamp...
Maybe this is a silly question but do I need to detune the truck before I go in? PCM software update is different and has nothing to do with the E85 tune?
Oil levels have been corrected, it was a quart low. I’m having trouble understanding how it could/would burn through a quart in roughly 3000 miles. Spark plugs and sensors will be changed tomorrow. I’ll reset the ECU again after they’re changed and see if that resolves.
Truck has 74,000, 2020. The most recent upgrades have been 1050cc injectors, spark plug change and an E85 tune. I’ve been running those three items for the last 3500 miles with no issues.
This morning I got off the interstate after going 15 miles, cruising at 72mph. I turned onto the hwy...
