P0705 / P1618 codes lit up:
My wife drives the S40 and came home today complaining that it was "acting funny". Knowing that meant trouble, I went out to look at it and saw the transmission light blinking and the check engine light on.
She told me it was idling low when she started it and sometimes while trying to accellerate on the drive home, it would lose power and just idle.
We had this problem last year and took it to the volvo dealership. After replacing both coils, everything seemed ok and we had no more problems this winter.
I drove it around the block and didn't notice the issue she was describing, so I checked the codes. P0705 and P1618 were in there, so it certainly sounds like a transmission sensor.
Can anyone more knowledgeable than myself lend their diagnosis abilities here? I'm happy to do some work on my own (sounds like this is a sensor I can replace myself, though I'm not certain if it's touchy to adjust), so if taking it to a dealer is smarter, I'm ok with that.

RE: P0705 / P1618 codes lit up:
Yeah, the car behaved fine today, but this is the same issue we were having last summer (and some of the winter). Every once in a while (usually three or four times a week), the car would simply lose power and engine codes would start flashing.
I'm ok with generally clearing the codes for now and seeing how long it takes to happen again, but I'm more interested in what the problem might be that keeps causing this issue.
