    I have a 99 Tacoma with the 2.7. K&N cold a air intake and headers. It has started running very rich. When idling, it will almost make your eyes burn. No codes showing up. Anyone have any ideas where to start looking? The air filter is clean. I am getting between 9 and 12 MPG. It is running great other wise.

    Clean your O2 and MAF sensors.

    I sucked some Seafoam through the brake booster vacuum line and cleaned the MAF. Seems to have done the trick.

    It runs easier, peppier and better throttle response. I no longer have the fuel smell.
