Hi All
I have a 2020 Bullitt and noticed something while the car was idling.
if I press the brake, when I release the rpm’s fluctuate before settling down again.
I connected the Sctx4 scanner and when idling everything is perfect. Measured lambda is bang on 1.00. But as I pump the brakes the readings drop to 0,83 which would be a rich mixture.
I do have some intermittent problems with the car in that it sometimes runs great and other times a little off.
is this normal ?.
or could I have a vacuum leak at the brake booster ?.
thanks
