Hi guy's Great forum found loads of usefully tips and repaired loads of little quirks e.g. door looms and cruise control. Have just got this car last month for family days out over summer. but before I'm confident for long run I'd like to sort this problem out. Issue is car idles and drives round town ok but if you floor the accelerator it's slow to pick up and engine sounds if i have a sports air filter fitted. Have done a diy service like oil, spark plugs and leads,air filter and oil filter. Have also followed on here and cleaned MAF sensor with carb cleaner. other issue is below wiper bulkhead is some unit with vac pipes that leaks air for a few seconds when engine turns off ? cant find any corroded pipes or exact place where air coming from. any ideas? Thanks Paul
