Would tightening the throttle cable improve throttle response greatly? I know the P5's aren't the most responsive cars on the planet, but there is a ridiculous delay from the time I press the accelerator to the time it decides to actually accelerate! It has improved somewhat with the intake/exhaust combo, and I'm going to give the ground wires a shot soon, but I was wondering if anyone has tried simply tightening the throttle cable. Is it easy to do? Thanks for any replies.
