Recently, I have issues with the throttle control. While idling, my engine speed varies by +/- 1-200 rpms. Also the engine has been running rough and sometimes stumbles. The ETS light comes on once in a while and then the Check Engine light.<p>Have others had these symptons?<p>NoCal V70RAWD

Re: ETS Warning Light (NoCal V70RAWD)

about 3 yrs ago my v70 XC 98 did that. I took it in for a "software" upgrade. The computer thinks the engine is running rich, cuts the fuel supply and the re-settle in. that's what mine did anyway. the software upgrade took care of it. kinda like Windows 98, second edition if you will!

Re: ETS Warning Light (dave g)

I did the same thing. The garage did a software upgrade. It still varies a little when it idles. But it does run alot smoother. I think the software patch did the trick. How much did your garage charge you for the s/w upgrade? It cost me $140.
