I have replaced Plugs, Wires, Cap, rotor, PCV valve. Some vacuum hoses etc. Also cleaned the throttle body on my 4Runner. 3.0 6. The engine runs runs rough and sluggish at idle, with loss of power throughout the rpm band. The truck will not pass smog and the tech told me the timing is 17 Degs advanced at 27. It does not burn oil, and the coolant does not burn off. So I do not believe its the head gasket although I have not done a compressioin check. Could this be a timing belt slippage issue? Need some help. Thanks
have the same problem?
