Noticing the engine light on, I took my sienna to autozone for
diagnosis. They informed me that there were multiple engine misfires
and to change the plugs. I changed cylinders 2,4,6,and 5...but am
having a hard time with 1 & 3 as they are against the firewall under
the intakes. Any suggestions to get to them?
