Hesitation!

[MichaelHirst]

Hi put the rs tuner pops and bangs map on my car yesterday and today had a hesitation in the lower revs for around 20 seconds and then Just went and hasn't come back! Any ideas? Had the car serviced with new plugs today. Cars running a induction kit , rs tuner, full milltek with decat. Any help would be grateful thanks

My car used to hesitate, especially pulling away in a high gear, but not as in too high a gear and going to stall. Turned out one of the spark plugs was loose (also had a similar problem when my step dad owned it and turned out to be a dodgey injector). If you have just changed the plugs, check this.
