"This is a Volvo problem so please don't flame me, but I hoped some of you Merc guys might have experienced the same thing. (I also posted on the Volvo board) This has started recently, but is VERY intermittent. At low rpm (1000-2000 or so) it will run fine, and then suddenly feel like it almost stalls. It's more of a severe stumble that lasts a second or so, then will run OK again. Sometimes the stumbles will come only a few seconds apart, sometimes it will stumble a couple times then run fine for a long time.
From slow speed trying to get on plane, it will stumble a couple times then catch and run OK. Feels like a bad carburetor accelerator pump would feel, except its fuel injected, so that's not it. New plugs, rotor, cap, none of which helped. Some of the plugs were a bit wet, but nothing real alarming. Any ideas?"
