Hi Guys

In need of HELP

I have been getting a fault on my car Focus ST 06, engine system fault, accelerator reduced & the Turbo gauge wud not go over. 1/4.So I had it in a garage where they said P2127 fault came up on machine so they cleaned up throttle body etc...,so I have got it bk a few hrs ago but no sign of fault yet but Turbo will still not go over 1/4 still which it did b4. I did fit a new stereo 2 months ago , wonder if I've made a bad connection or bad earth somewhere ??? I could really do with some help b 4 I take it bk to the garage next week, my car is my pride. & joy !!! Oh somebody said it cud be the battery as it mainly does it when I start it to go to work in the morning then when I leave work, switch engine on & off & sometimes it goes off !!!

battery is a possibility, but the turbo should be spooling more than 25%

Have you put a multimeter over the battery?

No, and now the fault is showing AGAIN

No, and now the fault is showing AGAIN

Last week they reset the fault and the gauge was ok for a couple of hours but then it started again

p2127 can also relate to the throttle pedal sensor
