Re: 2006 Sienna tune-up
Have you replaced the timing belt? The 2006 is the last year for the 3.3 L engine and timing belt.
I would also do the following:
(1) Drain the power steering fluid and replace that (can suck the fluid from the reservoir and replace.
(2) Clean the brake booster vacuum line with seafoam
(3) Clean the throttle body, throttle plate, and Idle Air Control valve.
