I think you need to check the entire length of the throttle cable for kinks or binding spots. Especially check where it goes through the firewall. If you have kink, replace it - better safe than sorry. If it seems OK, use some white lithium grease to lube all of the spots you can. Also hit the pedal pivit points, basically any part that has to move when you use the go-juice.
