Tahoe towed great, drug the trailer down 10+ miles of miserable washboard dirt road without an issue. I can’t imagine towing 7k+ with a stock half ton truck, must be mega sketch.

Anyway, ranger had a bunch of failures, A belt shredded and wiped out the EFan wires, easy trail fix as I had a spare belt and wires. Not sure what pulley is misaligned but I have a feeling it’s still somehow the PS pump. After that the starter for some reason committed suicide by staying engaged so I decided after 4 hours of riding it was time to head back to the truck. On the way back cruising 40 on fairly nice dirt roads, windows down, AC OFF, and temps nice and cool. An AC line from the drier decided to blow off and empty the entire AC system contents into the engine bay. Turns out there’s supposed to be a metal retaining clip for that line. When I did the system I never saw a clip and none of the new lines I bought came with one. Also, the line held on for 5 months of daily driving and blasting the AC the entire time, not sure why it just now decide to be ****.

All in all easy fixes and simple learning lessons. Can’t wait to put the midtravel beams and proper suspension on it.

As you all know I’m a shit tuner, and have struggled with some weird idle things forever. Mostly the truck would either stall when returning to idle, or would bounce around. Both are fairly dangerous because I have hydroboost brakes. So I hit the bullet and contacted Mail order tuner a guy who works with Texas speed and another buddy recommended. They are super legit! Within an hour of sending my initial email I got a phone call from the guy doing the tuning KC.

He said I did a pretty good job on the tune and wanted specifics about what I needed help with. Turns out my ECT Scalar (electronic throttle control), was way off. .0205 when it should have been .0255. Now idk what the **** that does and I’m struggling to find much info on it but I’m assuming it has to do with throttle body size, or throttle body motor parameters.

Right off the bat that helped and hes been dialing in the MAF a little bit better but noticed I was having a passenger side misfire between 1200-1600rpm and light throttle. So I pulled the plugs today which are iridium tipped NGK TR5s. They look mint as fuh, but I ordered some TR6s because that’s what I used to always run and I don’t remember why I switched down. Anyone have a good way to test coils? The misfire is not enough to make a code.
