so 2 hoses and a chk engine light...not too bad for that price.....guess im askin what do i have in store for me with 192k on it...and i saw the code list...how do i get the codes? do i have to take to shop?

 

A large hole in the intake tube sounds like it could be where the intake air temperature sensor goes. Look around for a couple of wires dangling.
As far as the transmission goes, start from a stop and count the upshifts. It sounds like you are in either 2nd or 3rd gear. By contrast, our 2001 runs somewhere under 2000rpm at that speed.
Pull the codes by doing a quick off-run dance with the key 3 times and they'll come up.

 

ok so off/on 3 times? then what?

 

Then the codes should be displayed in the odometer section of the cluster.
