after installing a cam and springs new opti and all the misc stuff. car ran great and i somehow or another left the key in the "assy" position all night.. when i noticed the next morning the battery was of course dead so i charged it and then when i ran the car i noticed that something wasnt right.. when u touch the throttle the car spits and sputters and will start to backfire.. no engine codes,, new ecu from PcmForless , changed the ing control mod, coil, opti, map,tps and i sent the ecu back to pcmforless and he just tested it and said everything is ok.. but will reprogram it and send it back.. now if that doesnt work .. what do you guys think??

 

maybe tune got ****ed

 

from my expiriences with lt1's if you don't have a good battery hooked to them they will not be friendly
