Hi guys, recently done an engine change on my OBD1 VR. Started up today and runs lumpy as anything When the engine is under load it fills the whole street with smoke and on idle the revs are hunting like mad. I really can't understand it as when we started the car after the engine change it idled beautifully. I have checked all breathers, plugs, hoses, oil level, water level etc. Any ideas guys? Don't want to but if I can't solve it this week I will have to break it to get some money back Cheers in advance
