well... £35 later and still no answer, their diagnostics brought nothing up just like when i did it myself, they put the pipes back on the bypass solenoid and the car isnt missing (even though it was before i bypassed it)
ive just got home, changed the pipes back so its bypassing it, gone round the block and everything seems fine
just one thing i forgot to ask them, its idling at 1000rpm, has done since i got it, this seems high to me personally, what do you think could be making it idle to high? plugs?
cheers, phil.
