So when I'm driving at a constant speed the car will begin to lurch as if it wants to stall but doesn't. I just had the fuel pump replaced by the dealer to fix the chirping issues and the only mod I have in the engine is an AEM intake. They told me it was bad ECU software and they rehashed it with brand new updated software and that still didn't fix the problem. Wondering if anyone else has seen our heard of this. Car is back at the dealer right now and I'm just wondering what kind of b.s. they might try to throw at me and if any of you all have suggestions.
