That is why I'm taking care of this cars maintenance now as If it HASN'T been done.

I've already changed the cabin air filters, intake air filter, oil, and was about to start changing the Tranny fluid and filter until I read somewhere that its supposed to have lifetime lubrication, and changing them would be tranny suicide. Idk. I scared not to get the tranny fluid and filter changed.
Wouldn't hurt to get some injector cleaners, also could be fault in mass air flow sensor.
