Really clutching at straws now ...
1.7 dti, 2004
misses a beat with quite ajolt once in 10 minutes generally only when warm.
The Engine warning light has never been on.
There's no smoke, no other symptoms, car in very fine shape other than this.
So far I have checked over the engine bay for leaks and loose connections, electrical and vacum there's nowt obvious.
I have replaced:
air filter, fuel filter and seals. I have been into the fuel pump ECU and resoldered the 'known' dodgy connection.
Surprisingly the pedal test threw up a MAF error code 0100 ( i have no idea when this was from though or if there could be more detail in the system)
As a result I have replaced the MAF with a new Bocsh one.
Still the problem persists and no more error codes with the pedal test
would a proper diagnostic show up anything else, I fear that I'm at the point of writing a blank cheque ... any one offer me a light at the end of this tunnel ??
reading here I'm thinking ..... it could be a number of things like
accelerator pedal unit
the list goes on.
