This is a problem with my 1997 TDI that went away for several years and has returned, but it is worse. When I am going up a hill and pushing the car past 75, the car suddenly loses power and the engine runs roughly. The car then has decreased power going up hills and will not go over 3,000 rpm. If I shut the car off and turn it on, it is back to normal, as long as I stay at lower speeds.
Previously I was able to turn the engine on and off and the problem would correct itself for a longer period of time. Now the problem will not go away.
I was at very high elevations in Mexico for several months, and the problem cropped up when I returned to lower elevations. That probably has nothing to do with anything, but I thought I would mention it.
The check engine light has gone on, but I am away from home and my mechanic and wanted to get a sense of the problem to see if I should get it addressed before my long drive home.
Thanks
