I have a 97 cobra mustang. it has a fully built crate motor with over 10k in just the motor With all the paperwork. I bought it for it home noticed it has a SCT4 tuner also. Well after the car gets good an warmed up, it would die, wait 15-20 minutes it will fire back up. Okay now here this the Turner is on it they said it had it over 3,800 no tunes need uploaded. Long story short this old girl talk my dad into telling tell him. Does she just need to master reset to Turner and the ECM also so now the car won't hit a lick a lick. I just need to know what recognition do I need to know about getting it back and lined out thanks
