i got the CEL (not flashing) and a bit of burnt smell when i drove for about 2-3 miles (i can smell from outside but stronger when i turned on the a/c).. went to autozone and got these codes: P0300, P0352, P0302.

when i started the car this morning and turned on the a/c the CEL started flashing.. when i turned it off, the CEL stayed lit (not flashing).. i took the car in for service today but drove the car there (about 31 miles drive) and it still smell burnt.

not sure if i made things worse.. well.. i hope not.. just wanted a bit of insight of what to expect (work, pay) for the service/fix in the dealership..
