So i have a 1993 golf mk3 1.6 petrol and i have no idea what the problem with the car is when i first start it and when its cold it idles at 1000rpm like normal and the first time i rev it or anything it comes down and idles at 1500rpm also when its warmed up the idle goes to 1,900rpm i havent noticed anything weird with it other than that it revs smothly comes down smoth turns off and on no problem its not jerky or anything
