KJ,

Thanks for the reply - and I went back and re-read your post. On further reflection, I did look into - briefly - a monitor like the one you used, but a duty cycle meter was much cheaper ($30 compared to $260), so I went that route.

Can I ask a few questions? Can you describe the "flapper" and "plunger" a little better? I'm not sure exactly what you are referencing here, nor do I understand how you adjusted it. And, which ECU are you talking about? I am assuming the MAS control unit behind the battery?? The CPS connects directly to the EZL on the left fender wall...is that the ECU you are talking about?

Also, my car is the M104 - does everything you talk about apply to my motor as well?

Thanks, Ryan
