This is driving me crazy. When I hit the gas more than easing on into it, hesitated for a split second before it goes. It's really annoying especially when trying to go in traffic. I recently had it dyno'd and a spark plug went out replaced the spark plug but the engine light came on. It gave me the code p1121. Replaced the tps and the tuner did an update and that took care of the light. The hesitation is still there. Cleaned IAC the maf and whole intake up to the throttle body. Set the tps at .98 closest to .99 as I could. Help with any info
