cranked then i turn it off and it will start right
up, i have put in a new battery, alternater,
changed map censor, replaced pcm. The
check engine light goes on and off and a

P0700 is just a generic code saying u have a transmission fault... u need a scantool capable of reading the tcm.. p0129 is sayin the baro is too low which comes from the map sensor with just the key on.. engine off intake pressure will be atmospheric pressure.. u need to find if this is an active code or a history code
