What's up guys so I disconnected my battery had to work on car and I got everything back together seem like it was running better. I cleaned the MAF and a vacuum hose from the BPV to the throttle body was disconnected I did this cause car through a caode for being to rich on a stage 2 from Cobb. Now that I hooked the battery up I took it for a drive seemed fine the next day got on it a little and the car cut out then back in CEL flicker then it go worst now the the car will start for m few seconds ad shut or like I turned it off the security light constantly stays after that. I thought maybe the tune did so I put it to a stage 1+ AEM nothing happened called someone who could reprogram the key he said it was already matched to the ECM the I asked if he could dig a little more and went to check immobilizer his scanner pretty much said there wasn't one there the code the is throwing is p1572 I've done so much research and here I am looking for someone opinion

Alright ill try it when I get home. Also i had it on a trickle charge for ever and it couldn't hold a charge. I had to jump it to flash the ECM, that helped out alot it actually started up. Before it would just crank, no spark or fuel.

Attempting to flash a map with a faulty charging system is asking for trouble. Make sure your battery and alternator are actually OK before proceeding.
