Please help! I ve got that jerkiness and hesitaion back again on my 1.8 lump. Had the EGR valve replaced a while back with no effect. Can a tech1 or 2 help? Am I correct in thinking if they wipe the slate clean then download software back onto the ECU it could smooth things out?
Any info or ideas would be great.
Another thing, can you think of any cheap/small engine parts that would benefit from a change due to tiredness and age that wouldnt normally be included in a service? The reason I say this is because my cars in pretty much perfect nick although the engine seems a little noisey from time to time and that jerkiness just lets it down.
