i just bought this car and after doing a full tuneup it still runs like a piece of crap. weak power, acceleration is not smooth, and sometimes it dies on me when it idles. for the tuneup i changed the sparkplugs, air filter, fuel filter, cleaned the mass airflow sensor, and changed the oil. the sparkplug wires look fine to me.

the check engine light is on so i brought it in for a diagnostic and they gave me the following codes after running it on the computer: 0113, 0102, and 1142. the guy told me to clean the "intake air temp sensor" but i can’t find it. i found the mass airflow sensor and cleaned that with a spray and put it back in….

how can i fix this darn thing? where is the intake air temp sensor?

also, for extra credit answer the following questions:

1. how do i get the "airbag" error light to turn off? can i just take out a fuse?

2. how do i get the seat heaters to work? i checked the fuse and it’s fine, but they still dont get hot.
