Took a trip to the UP in mid June, which was a GREAT time. Went with my buddy with his Macan. Camped near High Rock Bay 2 nights. Bugs were bad but survivable with good coverage clothing, permethrin, picaridin, and of course the patented cheap canopy with a net crudely attached. If you have dogs, keep an eye on them, as they can't protect themselves. Munched on quesadillas, Korean BBQ, Polish sausage. Checked out Delaware mine, did some hikes, can't wait to go back to be honest. Was gonna go to Shawnee but decided to take a risk on bugs in favor of not dealing with 90+ F day time temps. It paid off.
As for the truck, it seems like age, mileage, and lots of idle time are catching up to it. We are floating somewhere around 145k miles. That said, the last 45k miles were added in the last 3 years. The vehicle does a lot of idling, slow driving, package deliveries, awful Chicago traffic. Guessing this means it's got higher "mileage" in terms of engine hours than it would suggest on the odo.
Anyways, early May got codes P2445 and P0175. Installed the Gen 1 Hewitt Kit. Had a month+ and 2K miles+ of trouble free motoring. About 2 weeks ago, got codes P0418 and P0606. The battery was also weak as shown by starting issues on first try and slow cranking. Replaced battery, had about another week of code free driving when I got P0418, and P0172 and P0175. I'm thinking I've got two separate issues here brewing potentially. It seems P0606 can be caused by O2 sensor errors and/or weak battery. Battery is new and the code has not come back. Just P0418 and rich codes. Proxy pack on order to deal with the P0418. As for my diag so far on the rich codes. New Hitachi MAF. TB looks clean, was cleaned maybe a year or so ago. Ran fuel cleaner through it. So far nothing, codes have come back. I've ordered OEM O2 sensors, so now it's a game of what ships first. I think I'll be installing Proxy Pack first, although gut feeling is those issues are unrelated.
This exhaust was sadly a victim of getting rear ended a while back, and I'm not sure if the shock from the impact have caused issues, but that was 4 years ago at this point. Got a new eBay mid muffler on. Will need to remove the header heat shields to check on cracks, although mine does not sound all that bad compared to what I've seen/heard on YouTube. Guessing removing those heat shields is gonna end in them never going back on, but that's fine. Sounds like I should replace the original upstream O2s anyways as a maintenance item, so that'll be happening. I feel like I'll nail the issue here soon, but posting here for input and posterity.
