Hi all. I'm a first time Volvo owner although my fiancé has had a few. This car has been a pleasure to own, drive, and work on. It was in good condition when I bought it but past due on some maintainence. Since I've owned the car in the last 6 months I have replaced cap, rotor, plugs, wires, coil, crank speed sensor, engine coolant temp sensor, thermostat, air filter, cabin filter, tail gate panel repair kit, tail gate shocks, oil cap seal, cam seals, cam position sensor, all pads & rotors, motor mounts, and assorted vacuum lines and elbows. Even with all this maintainence the car still has an occasional hesitation/missfire under hard acceleration at high rpm. It's been an intermittent issue since the purchase and it use to throw Radom cylinder missfire codes. It no longer throws a code and however the sputter is less noticeable it's still there. It seems to happen on warmer days after the car has been driven for awhile. I haven't noticed it once on cool mornings or evenings or within 15 minutes of starting the car. Just hoping for some helpfull advice from a more knowledgeable Volvo owner than myself. Next on the list is fuel delivery but any advice would be greatly appreciated.
Thanks, Volvo rookie
