Thought id give you an update..After all the sweat and tears of buying and changing parts....IT turned out to be a faulty maf sensor ( brand new from dealership) was faulty...my mate did voltage test on maf....dead as a dodo...money returned as was not willing to wait 3 days for another...ended up buying second hand bosch maf from breakers £26.10....And michael knight eat you heart out...running perfect 1000% better and much smoother...
Wont have to service car now...New plugs, coils, egr valve, oil change and filter (magnatec), fuel filter, fuel pump, valve cover gaskets...£620 spent...when it could have been only £26:10...
Story of my life...
Thanks for the help mate...i learnt a few things along the way...valve covers were the worst job of all.
Cheers
