I bought a 1999 V70 XC with the ETS light on 3 years ago with 120,000 miles. The car now has 185,000 and I have not changed the throttle body. About once a month it goes into limp mode, I then shut if off, start it up and it is fine for a month or so until it happens again. We easily put 300
miles a week on the car.
So my questions are as follows:
1) what is the worst thing that could happen with the ETS light on other than the occasional limp mode?
2) Am I pushing my luck by not changing it or should I just wait for the worst to happen?
3) Is the fix an easy one? How much should I expect to spend?
