i have a 2003 wrx sti with 64k and my throttle pedal is stiff compared to my freinds hawkeye and classic!! do u think i should replace the cable and see how that gets on?? also when i take it to about 4500rpm and change gear the revs stick!! any ideas????????????????? cheers

 

Doesn't sound right at all. The revs sticking over 4500 could be dangerous. Get it checked out.
