Hey! I have a 1998 volvo v70 with a 2.4L engine. For quite a long time, it has had a noticeable loss of power nearly every time I drive it. On occasion, it feels like the the power is normal, -- I think this happens after a few days of relatively low humidity. Also, the gas mileage is nowhere near as good as it used to be. It seems like having the pedal down 1/4 of the way has the same effect as having it down 7/8 of the way. When the pedal is to the floor there is a noticeable throbbing from the engine. When the preformance is poor (as usual) the pedal needs to be to the floor in 2nd gear to accelerate onto a highway. When the power feels normal I can achieve the same acceleration with the pedal about 1/4 of the way down. Spark plugs were replaced 12,000 miles ago along with the plug wires and (I think) the cap and rotor. If I had to guess, I would say a weak distributor coil. Mechanic says its possibly a plugged catalytic converter. Thanks!
