Hi all I need help as I've almost given up on the car e21/320/6, problem as follows:-1. High Petrol Consumption Full Tank gets me 280km - Guzzler!!!2. Spark Plugs No 3, 5 & 6 - Carbon Build Up and Petrol Wet3. Strong Carbon Monoxide smell from the exhaustNotes:- Engine no knock, Engine Oil Remain Stable (No Reduction), No Black or White Smoke from the exhaust. What can be done, I have tried to tune up the Carb but nobody dare to touch in KL and Malacca, does the engine requires top overhaul and if yes how much can it cost? Please help now I am thinking of planting an e30 engine, however the car would lose on the originality!:stupid:
