Hi my name is Gene and while i don't own a car i do have a 2002 A15. the engine has the equivalent of 300,000 miles. I have checked your site for years when i need info for my engine . I hope y'all don't mind. It is the powerhouse for a carpet cleaning machine. its been having a strange problem lately that i have not been able to diagnose. it will go from 2500 rpms down to around 500-600 rpms and sound like its under water. it will run for 6-10 hrs a day just fine and somewhere during this time it will have this problem for maybe 5 minutes and then it goes away. i popped off the distributor cap and noticed the center contact for the rotor was completely gone. not sure how it would run at all but it does. i replaced it thinking that was the problem but it wasn't. i have the ignitor module but im not sure how to get it out. Do i push out that small pin to remove that gear ? i appreciate the help as it will probably be one way. Any ideas what would cause the strange problem. IT has the Mitsubishi distributor.
