    I am having issues with my 07 supercharged stalling while trying to pull out of a driveway at a higher speed. Sometimes it also does it accelerating around a corner really fast. The car usually will start back up when put in neutral and I can continue on. I do not see anything in scans that would indicate this issue. I have gotten it to do it on scans a few times but really don’t know what to scan for. Looks like the Maf is reading fine. From what I can tell there is no power steering pressure sensor for this to happen. It’s hard to diagnose since it is for the most part a random issue. Any suggestions??

    ive had issue with random stalling. I swapped the MAF even though scans were good and no codes, and it hasn't come back.

    No check engine light GTP.

    I was thinking the MAF as well mguzzo. It is only about a year old but that means nothing.

    What brand of maf is it? If it's not Hitachi/Delphi/ac delco, they don't have the greatest track record.

    It is a Delphi. What brand do you recommend?

    Another issue is this damn Pacesetter collector. It will not stop leaking. None of the muffler shops will touch it. I should eliminate them but it costs way too much. ZZP headers are over 1k so that’s not an option. I don’t have the stock Ported manifold setup anymore. eBay headers are garbage from what I’ve read.
    Local muffler shops wont touch my headers. A local Performance/ fabrication shop BDK Performance could probably fabricate something but will probably cost a ton. PITA!!!!

    pull the fuse box in the engine bay and look for the hi-speed fuel pump and bend tab 85 and see if it helps in the stalling when turning

    clic this link and go to post #8---> Fuel Pump Resistor

    Dumb question. How do I know which way the relay goes? Does the 8866 face forwards the left or right? I searched and can not find this information!

    Try the Crank Position Sensor.

    I had a very similar issue a while back, car would stall every day on the way to work. Right at the same place on the highway too.

    It could be difficult to test, but it's relatively simple to replace.

    Yeah, random dying without a code is a lot of times the crank position sensor.

    Update: I tried the relearn and it worked. The crank sensor is probably going bad.
