Asked by Aug 18, 2015 at 09:52 AM about the 2006 Toyota Sienna

Question type: Maintenance & Repair

The following services were done on my 2006 Sienna.
Throttle body service
Clamp L/F inner axle book
Front brake service(sealed bearing vehicles) replace font brake, pads, brake shims,
lube brake caliper slide pins and resurface brake rotors.
clean and adjust rear brakes
remove and replace leaking transmission pan gasket
remove and replace positive battery terminal
After taking the car home the engine light came up and the car started shaking. Took
back to the dealer and the engine check codes are 304,305, 354, and 356 - spark plug
problems. Could any of these be related to the servicing done on the car?

It's an ignition coil problem. Codes P0304 and P0305 are misfire codes for cylinders 4 and 5. They're not firing. Codes P0354 and P0356 are ignition coil codes. Sounds like they unplugged or moved around some wiring during the service and didn't put it back together correctly. Take it back. Definitely sounds like it's related to the recent service visit.
