My daugther's 96 tahoe has 150,400 miles. It is a 5.7 4x4.
I have recently replaced the water pump, plugs, plug wires, distributor cap and rotor.
My understanding is that the PCM and/or TCM is responsible for the P0700. How difficult is this to change?
The engine runs very smooth, so I'm assuming the P0420 is the catalytic converter. Any other suggestions?
I'm not sure about the P0172 and P0175. The oil is changed ever 3,000. Could the PCM (P0700 issue) be causing this?
have the same problem?
