January 29, 201115 yr 2000 outback wagon, 185k miles, auto I feel it in the gas pedal only, a roughness when accelerating lightly. If I put my foot in, it's smooth. I can't feel in the seat of my pants, only my right foot. It feels like an exhaust leak sounds, if that makes any sense. Plugs and wires have about 20k on them. I'm running mobil 1 oil changed at 7k to 10k intervals. Timing belt, oil pump, head gaskets, etc changed about 60k ago. No CEL. Thoughts?
January 29, 201115 yr Well, at full-throttle, a few things are ignored by the ECU. Like the O2 sensor signal. Part throttle has all the emissions control systems active. Except during warm up. So part throttle on a cold engine should resemble full throttle on a warm engine in terms of ECU monitoring. Pardon...just thinking "aloud"... How does it behave cold?
