2013 Srt 8 acceleration sag
Anyone have any trouble with an acceleration sag/delay? I was attempting to pass a semi as we both left a stop sign at about 35 mph, I got in the left lane and hit the gas and it lost power until I let off and pumped the throttle slightly and hit it again and then it accelerated quickly like it should have the first time. I did only have about 1/8 tank of gas I took it into town filled the tank and again jammed the accelerator down and it seemed to have the lag and it was making a deep intake sound like the old 4bbl carbs did. I switched the setting to "track" and tried it again. If I was above 25 MPH it would lag if under 25 MPH it would burn rubber on the roll and get right with it. A very moody car sometimes. The temp was around 87 today with high humidity but the car had never done that before even in higher outside temperatures. Any thoughts?
