Hi guys! First wanted to say that this place is an amazing resource for tinkering with my 944!
1st off, my problem: Car returns to idle when throttle is opened all the way (cuts out around 85% open) in all gears, even neutral.
Thought it was TPS, so I followed Clark's instructions on checking the DME plug for correct resistance readings. All was satisfactory. Does this mean that I don't need to remove throttle body to check actual switch <fingers crossed>?
I don't see any glaring problems with my vacuum lines...
When I disconnected the DME plug, I noticed that there was a plug with brown wires coming from it...see attachment...that wasn't connected to anything...is this the speed sensor? If the attachment doesn't show automatically, can someone tell me how to get images to display within the post? Thanks!
Thanks guys! Any help would be greatly appreciated!

Hey BKiller...you have my stapler? Great movie...
Not sure about the AFM...I just purchased the car. Definitely not hitting rev limiter...it'll cut out at any rpm...definitely when I get the throttle open the right amount. If I punch it real hard, it cuts before the revs have a chance to get up at all. How do I check the AFM?

Its possible the wiper track in the AFM is hitting a dead spot and is causing the cutout. Basically you need to power the AFM with a 9v battery and move the barn door through its range of movement, you can check the voltage with a multimeter. The voltage should raise up to roughly 8.5 - 9vs with the 9v battery source. If there is any voltage drop or voltage fluctuation your AFM is probably out of whack.
