My skoda fabia the traction light comes on when car turned on it runs fine for about a minute then the EPC & engine fault light come on and the car starts to struggle for revs.

when try to rev it just drops in revs.  iv had the throttle body changed the erg valve cleaned. Anyone else have this problem ?

@marko28 - Well, you clearly have a fault somewhere yes.

 

Have you tried investigating fault codes rather than just throwing money at the car? Does the ABS work correctly?

yep mechanic and friend put the Volkswagen machine on it threw up codes pointing to things like throttle body (changed that) erg cleaned but they were flummoxed said it possible the the computer it self.

UTTER nonsense, you're dealing with complete idiots wasting your money.

 

First off, fix ALL the vacuum leaks, there will be some in the brake servo line.

Second, test all the coil packs, failure is common and can give symptoms like you describe.

Finally post the codes here for a free reality check.
