At last my Galant Gdi 1.8ltr. auto has found a new garage!! Mitsubishi official garage did not manage to identify the problems of misfires and rough iddle although the engine was working like new whenever they started the car in the garage's yard. A friend of mine took the car from the dealers garage to take it to another garage as I found their customer service very poor (and I was at work all day) and surprise surprise...When he reached the highway less than a mile far from mitsubishi's garage the engine started working with three cylinders again and lost almost all its power, before stoping and refusing to start again!!!!! Anyway after the usual recovery service phone call and rescue, the car is now in a new garage. The mechanic has already replaced all 4 spark plugs as he said that one of them was full of water and also all 4 were fairly old. He is going to keep the car for one or two days maximum more in the garage to give the engine an overall check and cleaning all air intakes and hoses. After changing the spark plugs with new iridium ones the car already drives like a dream.
What the fuck was mitsubishi's mechanics were doing keeping the car inside their garage for more than one week ???????
I insisted when I had the car delivered to them to check the spark plugs and the fuel filter and have them changed anyway.
But they did not even bother!!!!!!!
I hope the problem with my engine was only the old spark plugs and the water inside the spark plug cable.
Now that the car is in the garage should I replace anything else for precaution reasons only in order to make my engine rev happier???
I have already changed oil, air filter and the front brake pads.
Thank you very much in advance
