Duty cycle is in the butter zone when the plate is deflected.

I think I've seen that tool... My big question would be if you could get the air filter on with the tool attached. Driving around w/o an air filter probably wouldn't help things... I was also hoping to sell the car later in the year to upgrade to a R129 or the like so I need a permanent solution.

The other thing that bugs me about how she's running is that the duty cycle is where I'd want it (5.5-6.5v & oscillating) after cold start before the car enters closed loop (or should) and it drops to .1v. Now, the reason that bugs me is that it still runs like crap during open loop even though it's showing a decent DC. However, if I deflect the plate even when it's cold, the idle smooths right out.

As soon as I get a chance this week, I'm going to try to adjust the AF Pot, because that is actually physically effected by the AF Plate. It tests fine, but I'll try anything right now...
