Default Toyota Avalon 2006 all Check Engine, VSC, Traction Control lights are on. Help!?

Hi. How are you awesome people?

I have an Avalon 2006 (123100 mileage), that has all the above lights ON. I went to car repair shop, and they scanned the codes. It came up with these; P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0356, C1201. What do you think?

I have the same type of car and mine has 130000 miles but mine had the same problem and the problem is the gas cap is letting air in and that's causing the light i replaced the cap it cost about $40 and everything went back to normal.

The Check Engine light is the one that matters. The VSC and Trac lights come on when the engine can't reliably generate power to make those functions work - when you get the check engine light to go away the others will clear.

What you have in those codes are P0300 random misfire, P0301-P0306 misfire in cylinders 1-6 (fits in with P0300), P0356 primary/secondary circuit fault in ignition coil 6, and C1201 computer stop (the way the ECU turns off the VSC and Trac). P0356 is the one to focus on. According to the source it is always cured by replacing the coil on the indicated spark plug... cylinder 6, in this case. Important note - there is a lot of old information that indicates cylinder 6 is against the firewall where the intake manifold has to be removed for access. As the source indicates, a TSB clarifies that cylinder 6 is in the much more accessible front driver side. If the mechanic says it is expensive because it is in the back you probably should shop around for a better mechanic. The dealer may be your best bet. The source also says Wells brand coils are more reliable than the OEM coils but you may not have a lot of choice depending on where you take it for repair.

Finally,. what is with the other misfire codes? Nobody seems to know but they appear to be standard with the coil failure.
