Car is a 73 2.0, new TPS, new FI Points, new TS1, existing TS2 (its the 017), all intake runners, hoses, gaskets, and PCV are new, injectors were cleaned and serviced by witchhunter. Also all parts are correct for the 73 2.0. I put a 270ohm resistor in too. Car seems to run lean at idle (I have an air fuel meter).

I had the wrong TS2, because I replaced it with what I thought was the correct replacement. Upon further review, I put the used 017 piece back in.

The car had been sitting when I bought it, so I dropped the motor to take care of a few problems, and I refurbed the FI while I was at it.

Car seems to have good power and pull hard, but it doesn't seem to idle quite right. It oscillates between, 1000 and less than 500, while the air meter reads lean. Air bleed and the knob both effect idle, but I can't get it to stabilize or richen up on the meter.

Also, I have a euro-race header and MSD. Should I play with the resistor or the FPR to richen the car for these parts?

OK so, I installed the new vacuum pod and un-deleted my retard. It definitely made a difference in the behavior of the idle. I re-timed the car and ran it around a bit. The idle was still hunting, so I stopped and made some adjustments. Now it idles pretty steady. It oscillates a few times and stabilizes. I have the knob fully rich, which bugs me a bit. Hopefully I can get it on the CO analyzer Saturday.

I also checked the dizzy shaft and its tight.

And, I checked my charging system and had a minor scare. I put my battery on a trickle charger before work to top it off, because its been sitting for almost a year. I used my DMM in the morning and it worked fine, but I forgot to shut it off. Charged the battery, home for lunch, test the battery in my running car at lunch. DMM is telling me 9Volts. I'm shitting but, eventually I suspect my meter. Test the car with another meter and it reads as expected. My DMM went south between breakfast and lunch!
