I have a 2002 Merc EFI 225hp motor. I had some problems with it last year and had to replace the crank and connecting rod and piston. By the end of last year and the first few times this year it was working ok. It seemed a little rough on idle so I took it to my mechanic who put a diagnostic tester on it and said the "map" sensor was faulty.So I had it replaced. When I took it out after that the motor worked terrible and wouldn't even get the boat on plane. Back to the mechanic I go and he says it is using a lot of oil, the plugs are all fouled. He also mentioned the throttle position sensor.
So what I would like to know is how can a "map" sensor cause me all these problems? Does it effect other sensors?
