I have a 2006 Pontiac GTO. Its has a 6.0 LS2 v8. I have a K&N cold air intake, magnaflow exhaust, no catilitic converters, and still has the OEM computer settings. The car tries to stall out and sometimes shuts off completly when you roll the windows down or if the A\C is on full and you stop at a read light. I just replaced the battery and the Alternator checked out fine. I cleaned the MAF sensor and this seem to help for about a few days but then it started again.
