hi ,ive had a problem a couple of months ago with the acelerator pedal the,rac man said it looks like the pedal was faulty ,as it didnt rev up .we put a second hand pedal on and it worked fine .then the problem came back again .so change the pedal again .it was fine for a few days now it goes in to limp mode .if i take the earth off the battery it most times will drive fine for the of the day .do the pedals need to be the same ,the second hand unit have been off the earlier 307 2.0 lt hdi.i took it to the peugeot dealer ,they told me there was too many fault codes on the ecu and it would cost more than the car is worth . ..any advise .thanks ray.
