2005 mustang gt, auto trans, stalls when I put it in gear but if I feather the throttle going into gear it drives fine, also if it does stall, it is very hard to restart.P0505 code on snap on scanner, also stated bad cylinder head temp sensor.

281cid stroked to 302, supercharged, 60 psi injectors, dual gt 500 pumps, comp cams.

Thanks!

Check for vacuum leaks. Clean the egr, IAC (if equipped) and the throttle body.
