    Hi...I have read about a port being blocked on the throttle body with carbon. Could you please tell me where this port is located. I am getting a timing ping under slight load and I am trying to check everything. I have reset the timing to 3 deg btdc with the terminal jumped. I did find a crack in the vac hose going to the throttle position switch.

    thank you,
    Eric
