I got a copy of the Carfax on this Enclave from him it looks like it was always serviced at the Buick and Chevy Dealership. It has it's original transmission never replaced and original timing chain never replaced.
He had Enclave inspected needs rear shocks rear upper control arms and New belt and need belt tensioner and pulley also need wheel alignment new rear brakes and new throttle body. Beside from that Enclave is in good shape.
I am getting code P2135 in my Buick enclave it came out to be bad throttle body can, I install the throttle body myself looks easy only see four blots holding it on and one connector that plugs into the back of the throttle body. Asking because dealership wants $661.00 to replace it.
