Using this link: k1100_motronic_2.1_by_Frank_Warner-1.pdf that was provided above in this thread by someone, I went to the motronic connection and did the following:
"1. Measure the resistance from pins 31 to 25, this should be 1k ohms +/- 10% and is the value of the pots resistance.
2. Measure the resistance from 28 to 25, this is the slider to the bottom resistance.
3. Measure the resistance from 28 to 31, this is the slider to the top resistance.
4. The slider resistances should approximately add up to the total measured value of the CO pots resistance. If either or both of the slider resistances are well above or below the CO pots', it is faulty - get a new one."
SO, I did these measurements and got the following:
-Pins 31 to 25 = 724 ohms (total for CO pot)
-Pins 28 to 25 = 1246 ohms (slider to bottom side)
-Pins 28 to 31 = 456 ohms (slider to top side)
1246 + 456 ≠ 724 at all.
-I need a new one.
From what I've learned from this thread, the CO pot can cause unevening running similar to what I'm experiencing with the misfiring. As such, I'll order a new one (probably used on ebay? because I'm a poor college kid) and pop it in, adjust a few things, and see what happens. I'll report back here when I get that done, probably in a week or so. I'd love a confirmation that I have done these procedures correctly and ordering the new CO pot is the correct course of action.
HUGE thanks in advance for all the help on this thread!
