Ok guys , done a straight swop on Monday with my 3lt manual terrano for a 3lt auto terrano.... Got onto the motorway ,lovely drive.. Pulled like a train smooth etc etc , after driving for an hour or so ,masses of whitish smoke plus oil and engine light on.. Pulled over , turned engine off for 10 mins started her up , back to normal... The next morning started her up , ran like a dog with so much exhaust smoke couldn't see for 10 mins!!! Got my machanic out same day and after putting on the computer ended up changing the fuel filter and emptying the fuel pipes and fuel tank .... Started her up and she ran fantastic !!! Went out today and again running lovely until I went up a slight hill, the engine light on then oil light then loss of power and a bit of smoke... Stopped 5 mins , then started her up back to normal... What's going on??? Please help guys otherwise this could be the last Nissan I own , I really like the auto and when it's running it feels like it would pull a house down but it's so really want to keep her ! Cheers rob
