12th Jun 08 Guys I am so impressed with your service, ordered yesterday pm arrived in post this morning and fitted before I set off for work Results still being assess but already engine is smoother (now like a V6) problems when cold ie running very rough, if it were a petrol engine I would think a plug had failed, have been reduced and hopefully eliminated. Need a few more cold starts to confirm this None of above could be cured by Vauxhall And pick up in gears wow !!! even in sixth !! Deadspots what deadspots. Further up date after more miles but so far very impressed A nylon tag to hold main unit would be good idea, it has the lugs, and some waterproofing around DIN connector Thanks again Nick D
