Rough idling after cold start and fuel smell
Hey folks,
First time poster, as I recently purchased a 2004 V70. Purchased the car about 3 months ago and for the first 2 months it drove great. Then it sat for about a month (registration delay due to Covid-19). I finally got it back on the road the other day and when I went out to start it, the battery was dead but it boosted right up. First thing I noticed was after the first start, it idled pretty rough for about 30 seconds, then smoothed out once I started driving. Been driving it for a few days now, and every time I start it cold in the morning, it is a little slow to start, and again idles rough for a few seconds, then it's fine. Starting it warm (for example, after I come back out from the store or something) it starts up just fine. It doesn't misfire or surge or anything like that while driving, it's only right after a cold start.
Another issue that I'm not sure is related: I've noticed a fuel smell after parking it. Seems like it's coming from the rear passenger side (exhaust maybe?) but it only began when the rough idling began, so I think they could be related.
Would really appreciate any ideas of what the issue could be! I'm only mildly handy with cars, but I was thinking some sort of vacuum issue, spark plugs, or maybe MAF sensor? That's just a guess though and could be off base.
Thanks!
