What size are the botls on the Throttle body that hold on the TPS sensor, and what size are the bolts that hold on the bottom coolant passage. Also what is the best way to get these bolts out i broke the heads off a bunch of them and the rest does not want to come out

 

IIRC, the TPS screws are M2.5. The water passage cover on the bottom I can't recall, but I've had mine off and it was no picnic. Soaking in penetrating oil and heat can help. Once you finally get all the screws out, use anti-seize compound when you reassemble, and you won't have that problem in the future.
