Toyota Repair: 2007 Toyota Camry

Question
My 2007 Toyota Camry XLE has about 72,000 miles on it.It is a 6 cylinder 3.5L engine. I bought it pre-owned 4 months ago with no warranty. When I started it in the morning and started driving after a couple hundred feet the check engine light came on, the VSC TRAC light came on, and a message displayed saying “Check VSC System” As I kept on driving it, it started to get shaky. I took the car to a local AutoZone and had them check to see what the cause of it was. The trouble codes that were displayed are; P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0356. What could the problem be? Is it really bad?  

Answer
These are engine misfire codes, possibly a bad igniton coil which is fairly common on these models, it should not be driven a lot with the misfire as this can damage the catalityc converter. The VSC TRAC lights will automatically turn on whenever the check engine light turns on and there is probably nothing wrong with those systems.
