I have a 92 SC300 that has had a periodic problem since I have owned the car. I am the second owner with 117,000 miles. I have replaced two O2 sensors and lubricated the linkage but still have an intermittent problem. My gas pedal at times is hard to depress. It gets stuck in only the upward position. I have removed the mats and as previously stated greased the ignition cable. The car was never in an accident. I can't get it to stick when I take it in for service. Anyone have any ideas I'm at a lost.
