Lately when I drive the car the TPS has been moving on me(not in a good way), I'll have it set at .42 idle take the car out and after a couple WOT blast the idle will be at .50 or higher. I spent an hour at the hardware store the other day looking for replacement screws with a hex or allen wrench head to get some more torque on it, the closest I could come up with is a 10/32 bolt but the threads are a different pitch and I can only screw it in a couple turns. Does anyone out know any tricks or better yet know the actual bolt size for the TPS?? I can only tighten it so far with a screwdriver.
