Thanks for the suggestion...we've added fuel injector cleaner, and checked the filters.
Mechanic has visited again, not found the core problem, and is still guessing at bad gas.
All I know, is that this is giving ME bad gas....
Obtaining a 2nd opinion, hopefully, today.
Trying to avoid the expense and downtime of fuel polishing, plus, we haven't found anyone that can perform this service in the Burlington, Ont. area.
I read the specs on the Seafoam, and it sounds very interesting.
Have forwarded your message over to my hubby, too.
We are dock bound til this is resolved, because I don't have confidence in the engine performance, especially for when we are going out and coming back in from the dock!
