Hello Chevy CC,
I have a 2013 Sonic Lt Hatch 1.8L that I've change the fuel pump, valve cover, purge vale, and ignition coil. Dealer wont give me straight answer, telling me they have to keep diagnosing.
I am getting a P0304. There is still def a misfire with check engine light on.
Could it be I purchased a bad ignition coil? what could be causing this?
This car did not make it thru the life of the loan! This is not good. at 101,000 GM should at least diagnose this for free instead of me paying $150 a third time!
Please help.
