Brew- Looks like we are in this together!

I'm sure you have read through the thread entitled "duty cycle sticks at 10%." Some good info there.

I will finally have some time the next few days to get serious about fixing this problem. I plan to follow the advice given here and pull the potentiometer. I will post pictues here as soon as I do and maybe we can continue to compare notes. By the way- what type of cold starting symptons so you have, if any?

I will try your "floor it" method and see if I get similar results.

Can one unplug the potentiometer and still run the car? What should happen if it is unplugged?

When the potentiometer is taken off the AFM, what type of precautions must be taken as far as marking positions and so on?

merry christmas guys!

Mike
