Question about 2003 Toyota Corolla
This vehicle automatically adjusts to altitude changes. There are no jets to change. It has multi port fuel injection. This may be a problem with the o2 sensors. If the check engine light is on then I would have the codes checked. If the light is not on then you may be able to solve this with a thorough tune up. i.e. plugs, wires, fuel filter, air filter and oil change. Hope this helps. Good luck.
