Charged battery and now codes: P300, 301 & 305
Battery low-light on for a week then no start. Charged from under hood and holding charge three days now. Problem... ruff idle and OBD error P300, 301 & 305. Plugs and coils replaced 5 years ago. Any quick checks prior to having looked at? Had other minor concerns dropping car off for, but don't want to drive with misfiring cylinders. Dash displays errors... engine malfunction and increased emissions. Any suggestions and/or cautions? Thanks!!!
