thanks for the info. After doing some reading from modified.com with them modding the focus including putting on the lightweight flywheel from focussport, i've come to realize a potential issue as to why some people may be having this stalling out problem. The sensor... ahh i'll quote the paragraph and paste a link:

Hope this helps everyone out:

Quote:The ECU monitors engine speed with a Hall-effect sensor that can sense a piece of ferrous metal passing. In many cases, these crank sensors are simply wheels with a series of square teeth cut in them, but on the Focus a series of recesses are drilled into the back of the flywheel and the metal left between each hole is what triggers the sensor. Of course, Hall effect sensors can't see aluminum passing, so with FocusSport's aluminum flywheel, the holes (or more precisely, the metal between the holes) had to be replaced with a series of steel pegs. It's a little more complicated than your average flywheel, but the sensor continues to work perfectly.

Project Ford Focus - Pt. 2

At the bottom of the page there is a picture of the two flywheels with a small paragraph that reads:

Quote:A series of holes in the back of the stock flywheel serves as a crank angle sensor. On the FocusSport flywheel, steel pegs serve the same purpose.

Maybe this is your problem? Whats great about this project and write-up is they really go into enough detail to help provide some level of education to the ones that don't know a thing, ex. myself.

My flywheel on the focus is starting to warp (or so it sounds, haven't seen ripped it apart yet) so I have been looking at what options are available to me at a decent cost. Basically at the end of the day, I'd like to do what needs to be done to the tranny and be done with it, hopefully never having to replace anything *crosses fingers for future* :P
