The thing sticks when it wants. I have oiled the shaft, reset the iac,and checked the tps with a meter. The tps is new and checked out at 4.8v input, .8v idle, and 4.8v wot. The iac is old, very old. The tb is stock bored to 52 ,the people who modded it did not change the shaft bearing. I,m leaning towards iac being the problem or should I check something else I might be over looking? Also thinking slight vacum in the tb shaft .
