My 01 VW Jetta with 181690 miles started having intermittent loss of power a year ago:
- it never conks out; 2) it loses power on the highway at 70 or in town at 25; 3) engine is usually hot, about an hour into a trip, but now does it cold, too; 4) weather doesn’t matter: dry or wet; 5) check engine light flashes while it happens 6) it feels like it’s running out of gas but isn’t.
Mechanics have tried the following: Note: every time I brought it in to be looked at, the symptoms above were happening
1)March 2013: replaced coil pack and it ran fine until Sep; 2) Sep 2013: ran Dx on check engine light: “arching all over the place” so replace spark plug wires; 3)dec 2013: got oil changed 4)Jan 2014: ran Dx and was told crack in piston; 5) Jan 2014: got second opinion and told wrong spark plugs were used (single electrode vs triple electrode)-replaced all spark plugs; got car inspected and had oil changed again as it was dirty; 5)feb 2014 mechanic is stumped, but found an article about clean oil and changed the oil again. Oil was down almost a quart.
Thoughts or suggestions?
