check your pm's, the answer is in your original post on what is wrong. i had the same problem in my si. the car used to die without the clutch pressed in, rolling, stopped. i think it stalled 36 times on sugarloaf one day in traffic.a few things need to be adjusted right. the guy who did your timing probably has it advanced way too far, and b/c of that he had to mess with the idle screw. when the other guy adjusted your timing did he jump the ecu(paperclip)?
