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
