I have a 99, S70 (5-speed, non-turbo) which has had a idle problem for some time. I finally decided to take it into the dealer, and asked them to trouble shoot the problem. They read the codes, and came back with an electronic throttle module which apparently has an intermittent problem. The are quoting about $1000 to replace it.

So, with 500 miles left on my extend-o warranty, I figured that I was covered. However, the good folks at the warranty company executed one of their stand by loop holes, declaring this part a "emissions and/or exhaust" part there by eliminating their liablity :). Nice. I have a couple of questions, and would like to hear what others think:


- Does the Electronic Throttle Control mean ECM?
- Is this a difficult thing to replace, and should I attempt to do so
my self?
- Would anyone consider the throttle control unit to be a piece of emissions
equipment?
- Is the Throttle Control responsible for other functions, that may be
covered by my warranty (ignition timing, for instance)?
- I've seen many posts about this part failing .... has anyone had luck
with contacting Volvo about this part? Should I complain? (The problem
has been mis-diagnosed for about 3 years on my car).


Thanks In Advance
