    Also @andrewclaus thanks for the info about aftermarket cats. The first garage said it would be $600 and just bring it in and they'll put in the cat. The second garage said it would be $250 and to bring in the car a week before the cat gets put on so that they can actually diagnose the problem.

    I just got a 2005 Prius with 292k miles and same problems. The noise is coming from the timing chain/valve area. I tried cleaning fuel injectors, new spark plugs, cleaning sensors. Battery stays at one bar on highway. Flooring it gives little acceleration. No error codes. 25 mpg/tank.

    Did the new cat help?
    My next step is to try more fuel system cleaner. Dont care about the ticking noise but need good mpg.
