I would appreciate some help figuring out thse codes. The issue only comes after the engine gets up to temperature or after a few good miles of driving. The 4 codes are: P0303, P1316 no DTC (dont know what that means),P0353, P0353 (twice?) I've done research on here and understand that PO303 is a misfire on cylinder 3. But which # 3 side? Also P0353 was a duplicate code and it spears to be coil # 3? Does that mean it will be the coil on cylinder 3? Could someone please clarify that for me? Thank you.

 

Anybody home?
