I finally got around to installing the set of sprint 520 injectors in my car, and adjusted the IQ down (up?) Into the 5-6 range.
It's much happier now, rather than the 1.2 it was running before hammer adjustment was done.
That said, I wasn't able to get the old injector washers out of the head.
The last set that I used were aluminum, (when I pulled the 520 injectors due to a broken spring) and seem to have bonded with the head. I couldn't get any of them to budge.
I finally gave up and tapped the injectors into place with a drift to seat them against the old set of seal washers, and they appear to be sealed at the moment...
edit:
I forgot to mention polishing the headlights yesterday as well.
3M headlight kit that I lucked into at Goodwill for $10, plus a can of Meguiar's headlight clear coat.
Just by accident I managed to find a trick to make the polish kit last FAR longer than 3M's instructions suggest it's supposed to.
Keep rinsing the headlight and sand paper free of the plastic being sanded off. That's it.
I have a misting sprayer that I had filled up with distilled water for a tint project I haven't gotten around to yet, and just kept pumping it up and misting the headlight lenses clean after every pass or two with the sanding discs. I never clogged or wore out the first 500 grit disc, and I don't think I really wore out the first 800 grit disc either.
The final step with the polish compound only uses a tiny bit of the package, so that was just stored in a zip close bag for another use in the future (though I might resort to Novus plastic polish if the 3M stuff dries up.)
The whole process did make a HUGE mess, slinging splatters of plastic dust all over the area, some even landed on my windshield.
Masking off with trash bags worked to protect the hood and grill near the lights, but the splatters were far beyond where I though they would spray.
