At last after a new set of spark plugs and a thorough engine clean, my car drives near perfect again. My mechanic (the new one, not the others from mitsubishi garage that did not even bother whats wrong with the car) told me that it is wise to change also the spark plug wires and their coils.
Unfortunately in Cyprus the car was only imported from private dealers straight from Japan, meaning that it is very difficult to source any parts (particularly electrical stuff). One possibility is to order them from the official Mitsubishi dealership, although it is going to take at least a month before I have them delivered from Japan. Does anybody know where can I find a source for parts for my car (except from ebay) e.g. spark plug wires and coils??????
The car is a 1998 Mitsubishi Galant GDI 1.8 automatic right hand drive.
Thank you very much
