Fixed my issue. It ended up being a damaged and grounded out O2 sensor power supply wire (B1,S1). Kept blowing the EFI No. 2 fuse causing the MAF to have no power. What an absolute pain in the ass to trace down.
I swapped in my old throttle body (still worked) and that didn't help. I did find some melted wires to the Bank 2 upstream O2 sensor, tucked up between the engine and firewall. After hours of loosening up the harness and disconnecting things, I cut the melted section out and repaired the wires...
Swapped o2s from a friends rig and that didn’t do it. I have new ones to go with the new exhaust manifold and cat for DS (~$490 from Toyota for the cat and gasket, O2s are denso from RokAuto), just haven’t had time to install it. Had been running fine for months with the p0420 until last...
Was a clogged cat the issue? I’m having the same symptoms with a P0420 (for 6+ months) and P0101 and P0102 (MAF) codes since it started cutting power at 2800 rpm this weekend.
Thank you for following my build! I appreciate it. I do not have a body lift and never will. In my opinion body lifts raise the center of gravity without adding much benefit IF you're willing to do the work to clearance for bigger tires. No doubt a 2" body lift would have saved me a lot of wheel...
Front bumper build

I'm gonna update this build thread over the next few weeks. It'll take some time because the 4Runner has been through a lot of changes since my last post, and it's currently in the garage undergoing a full suspension overhaul. This is my setup before the overhaul began. It was a solid setup that...
MetalTech MT-GSJ-4005 coils are for sale. Asking $150. Will ship at buyer's expense. They were on my truck for 8 months. Removed them when I added a CBI bumper. They were great coils with a cargo box, roof rack, roof top tent, and gear/water. Not heavy enough for all that plus 300lbs of rear...
I have 4x 2016 TE Rims for sale. Had them on my 4th gen for about 2 years. One of them is scuffed from off roading. The other 3 are in pretty good condition. Photos are here. I tried to show all scuffs. Make me an offer
