    Hey!

    I was talking to anotehr Prius owner about my problems and he started talking about his problems, I thought I would post it here to help him out a bit.

    He has a 2007, with a new hybrid battery.

    But after he got it back from the shop, (he tells me) "There is a ticking sound from the engine compartment. The car loses power when you apply full throttle."

    I told him I'll ask you guys as I trust you guys more than the local mechanics here :)

    Any idea what the problem/s could be?

    It would be much better for your friend to create an account and create threads and add posts. When the information is going through a third person (you), things get lost in translation.

    I'll guess clogged catalyst with a little of the exhaust being forced to escape elsewhere

    ...and that really is a guess, so don't give it much weight.

    Why was it in the shop?

    I agree, have your friend post here directly.

    My friend is on the older side, while most in Sweden speak English the older folk are kind of shy... and don't write in English.

    Car was in the shop to change the battery.

    Which battery? The hybrid battery or the 12v battery.
