Hi All, I have a 1997 Mk3 Automatic golf with the 1.8 engine. It has the eco gearbox. My question is - Does any one know at what revs the car should be cruising at while doing 70mph? The revs seem quite high at between 3 - 4000 rpm at 70mph (most autos iv,e had '1800cc' cruise at around 2 - 3000`rpm. Also the car seems to rev fairly high while climbing steep hills at between 3 - 4000 rpm. and even stays at these revs for about 15 seconds while back on level ground? Normal driving below 60mph except for steep hills is perfect. I am wondering if the above syptoms could be completely normal for this car or not? I await your comments. Simon
