    Running Rich

    Probably time for a new Denso O2 sensor. Also reset the ECM and possibly reseat the chip. Weird things can happen. No idea on the bluetooth.

    Fender roller for TB community

    I worked well for a long time but eventually someone broke it and skipped out.

    ECM prom cover and screws needed

    Cut one out of an old piece of aluminum gutter, round the corners, sand it with 600 grit sandpaper, drill two holes, voila.

    Should I coat/rustproof floorpans?

    I have used KBS Coatings on many projects and it works. I did a set of wheels on my utility trailer that sits outdoors 5 years ago and they are still rust free. They ship by mail too.

    Bent same pushrod twice

    I would be more inclined to suspect a bent rocker arm from the original incident that allowed the push rod to get off kilter and be damaged. It would be hard to imagine spring bind on a stock valvetrain with stock replacement springs.

    Part ID

    I was going to say flux capacitor. No more time travel for you.

    Running better but not the best.

    I thought injectors are 0-5v square wave? Pull your chip out of the computer and check it for bent pins. Reinsert the chip and see how it runs, of course disconnect the computer power wire first. Sometimes this fixes oddities. Your codes are about the MAF readings.

    Showing some love to the GN - Time for updates - Looking for Advice

    Valve springs are easy, need the rocker arm tool, valve springs and a handful of extra keepers in case one or two go flying. Comp Cam 980-12 springs unless someone knows better. Use cork valve cover gaskets, not sure about rear main as I never did mine. Not sure you need a turbo, the chip and...

    I do hear that the Goodmark fillers are pretty awesome like original.

    Painting fillers

    R&E Paint Supply used to be a good source to buy paint online and will ship smaller quantities. I did my own fillers at home - the originals finally dry rotted and fell apart. I bought a can of black base coat and a can of 2K urethane clear. I prepped them first, sanding and priming until I...

    Catalytic converter / exhaust support bracket for 4” single shot ?

    Muffler shops put those little L brackets on all the time for the rubber hangers. Maybe its a good time to wire it in place and take it there? For probably $50 they can do something custom and save alot of headache in a few minutes.

    Losing Power at WOT - No Codes

    60# injectors and E85 does not sound good to me. Since E85 needs 30% more volume that makes your injectors effectively 42s. Sounds like time to step way up.

    Stock-ish spiral air intake duct

    No sir. It's a one foot long connector, smooth enough inside that I see no issue. The pro cars always do better with no restrictions of any kind, turbos hanging out the hood or through the grille with an inlet bell. With a MAF and an aircleaner, there is going to be a restriction of some kind...
