Same scenario except one variation . . . their is no Sprint Booster on my NA .
I had this occur on my stock N/A with the standard 68mm Thottle Body and MAF Housing set up , for the first time last Fall .It happen only one time and it was after one fast demand of power with the pedal to the floor, that included the actuation of the switch at the end of the gas pedal travel .
Observations : an instant loss of power that should corespond to pedal position , like a dead spot and include , no throttle response to pedal input in the first half of pedal travel, then power would progressively come on .Even with the pedal to the floor ,the car still accelerate progressively like the throttle body is not completely fully open . No code generated neither .
I had this occur again recently . . . but now my N/A has the 74mm Throttle Body and 74mm MAF Housing with original MAF sensor in it . I was testing the added power and engine response of this new set up , on a desert contry road , the new to me , 74mm set up that I had done about 300 Kilometers before ,but ,it happen this time with one variant ,since it was after MANY fast demand of power with the pedal to the floor, that included the actuation of the switch at the end of the gas pedal travel . .The observations where the same has last Fall except for the fact of the rate of accelaration was little bit faster . . . so it is not evidently related to the TB
Last Fall ,an simple engine shut off and restart got rid of the problem .This time I used an Throttle reset but since it include an engine shut down ,it is hard to say if the throttle reset was necessary .No code generated or pulled out from the car computer with my OBD2 code reader " Launch CReader VI + " .
Is might be related to . . . the switch behind the gas pedal , the sensor of the pedal itself ,anything between gas pedal and TB ,wire ,electronical , informatic , an too fast pedal action or a combinaison of some of these factors. At least we do not get stuck on the side of the road but at the moment it happen it could have an dangerous end if it happen while passing another road user on a busy two way road .
