High Idle
 

Ok sorry guys and gals I'm new. i have a 2007 mazda 3 with a PO507 code. but it's not what it seems. the only time i can get it to do the high RPM is when the clutch is in and its in gear. if it's in neutral and clutch out its fine and when its in neutral clutch in it's fine.. ive cleaned the airflow senser, cleaned the throttle body and the 02 senser and nothing, the light comes back on. i cant find any air leaks and made sure the gas cap was on tight.... ive heard of the clutch switch going bad but i dont think it's that. and a guy from the shop said he thinks it's a thing called force shift or something like that in the trans where his friend found something online that u take the connection out of the trans and it's like a bypass for the high idle and cel. but i cant find it... oh if u didnt know it's a 2.0 5 speed, k&n (a year old), corksports exhaust (month and a half old) and a set of eibach sportline springs and koni struts and shocks. if anyone can steer me in the right direction on the code it would help greatly and thanks, i'll return my experiance if i can. thanks again Chad

ok i found it, it's the connection that goes to the tranny to a sensor on the tranny by the exhaust.. can anyone tell me the actual name for that sensor please?
