just finished this... wow! the throttle body was insanely difficult to remove because all the screws strip easily so I just left them in place and removed the 3 back bolts and there is a rod attached to it with a bolt on the top and bottom, the top was impossible to get to so I just did the bottom. and there is one more 10mm bolt in the back that I had to undo before I could pull that out and get to the spark plugs. Thanks for the info this thread really helped
