Ignition Control 700

I just wanted to thank all the Brick Heads for some very useful info. I just had my 1989 740GL(non-Turbo) returned to me in great shape!! I had the problem that was referenced several times about the poor idle and the loss of power while driving. It turnied out to be the Ignition control module. After replacing may other parts(that needed to be replaced) we finally found the problem. I suggest going right o the ICM before spending the $$ I did.(no Comment) Also, if your brick is running rough and is sluggish, try replacing the Flame Trap. It is usually located under the intake manifold.
Again, Thank you for all the information, I will be sure to check the BRICKYARD for all my Volvo needs.
P.S. What's the best website for parts???

    FCP Groton seems to be the most popular parts source for Brickboarders. There are other good sources that you will see mentioned in various posts and in the FAQ. FCP Groton are at www.fcpgroton.com. Their website has most of the commonly needed parts, and they have other parts that are not listed on their website if you call them. IPD (www.ipdusa.com) have some good/unusual specialty parts and tools but are a little expensive for the run of the mill stuff.

        You might want to re-post and ask that specific question. You will likely get a few good responses from people more knowledgable than me. Over the years I have had several odd performance problems kinda like this that ended up being due to bad/loose/leaky vacuum hoses, so that is usually the first place I look. The hesistation and missing might be due to a bad vacuum hose to the fuel pressure regulator. A new one will cost less than $1 from you local NAPA. Other than that, check out the 700/900 FAQ section "engine tune-up & performance". You might find something there that helps.
        Good luck,
