Thanks for the reply I appreciate it.
Regular oil changes and air filter; yes. Thought it might be the fuel filter, so I changed it, so that?s new. I have not changed the spark plugs or wires. The check engine light is not on. When I purchased the car 18 months ago it ran fine. Last summer it started acting up and I have not driven it much since. I have not worked on it much either, because it ran fine in the winter for what I needed.
I bought the care from a kindly old European man and thought it would be a safe bet, however it just now occurs to me that the autobahn is in Europe. Say la vie.
