Hi John Many thanks for getting back to me sorry for late response. Yes, I did follow these instructions. Unfortunately, things have got progressively worse and now I have a van that won't start at all with all manner of warning lights lit up!! Not good At a total loss really, so much so that I've had to book it into the dealership for diagnostics! Something, I fear, that is going to prove very costly, possibly too costly for me :-( Any pearls of wisdom will be greatly received at this juncture Thanks again for getting back to me John
