jerky acceleration

[Mini HeHa]

hi , only had mcs for several weeks and noticed slight jerky response on acceleration
seems to be on first squeeze on gas pedal there is a noticable blip...
running with typhoon induction anb borla exhaust , not sure iof this is normal or not...
was thinking new plugs might sort it or is this just normal.

it is fairly normal and is caused by the bypass valve or so I am lead to believe. mine still does it for the first pull off

Do you mean on and off jerky or kind of like it tries to go and then doesnt and then does again?

Sounds like a plug failure!

Mine was jerky and if you tried to rev it with any kind of power when it was cold it would cut out or go eratic for a second and that was down to the T-MAP sensor.

hi , many thanks for replies,
best way to describe is when stationary or driving and depress throttle there seems to be a momentary gap before engine revs increase..
almost like a missrire . it seems to be on first press of pedal...

My car jerks when you slow down to 15 to 20 mph then start to put the gas back on it then really comes in with a jerk . For the first 13,000 miles it was fine bmw said it was the injectors coming back in.

I had that hesitation, I think it's normal in minis due to the e-throttle or whatever, apparently a sprintbooster will do the trick, I just did the VGS mod, and it seems to be working pretty well
