dremel tool is your best friend when fooling with the tps ! ... u cut slots in the rivets and take a flat head screw driver and unscrew them !! then replace with a screw incase further problems occur .... i remind u put the tps back in same place as u take it off or mess with it a lil while the car is cranked if the tps doesnt make the idle fluctuate bad/better ... id replace TPS .thought id look out .. and g/l
