    ETM is probably the cause. The throttle position switch seldom fails in these cars. If you have a code reader try to clear the code before you start the engine and see if it runs better for a bit.

    If your ETM has a yellow tag on it it is a newer one. The dealer will charge you a fortune for a replacement, www.xemodex.com charges about $500+.

      Thank you Klaus C my local Volvo dealer replaced my ETM on my 2001 V70 wagon at no charge because the car was originally sold in 2002 so I meet the 10yr 200,000 mile extended warranty.

      I want to say that with Brickboard and Klus C I have the full support of Volvo family that I love."smlie"

      keep up the good work"""""
