last night when driving home the car started to stutter or cut back under acceleartion.
disconnected maf still the same, connected snap on ethos diagnostic tester 3 intermittent faults.
1. maf signal too low
2. coolant temp sensor
3. throttle body position sensor. signal not plausible.

cleared faults went 25 mile road test from hard acceleration to driving normal car drove faultless rechecked using ethos no dtcs, but when my girlfriend took the car to work she called to say the car is jerky when engine is under load
battery charging 14.2volts, cant see any split pipes, no lights on dash, car only run on shell or bp fuel.

1.boost pressure too low
2. boost pressure signal not plausible.
