1998 Toyota Avalon 6 cyl Two Wheel Drive Automatic 230000 miles
I am getting codes for cylinder 2, 5 and random cylinder misfires. I changed all spark plugs, replaced the PCV valve just for good measure, and changed the wire set. First, I want to make sure that I replaced the wires in the correct order. It is my understanding that the back cylinders are 1, 3, 5 from left to right if viewed from the front of the vehicle and the front cylinders are 2, 4, 6 again, from left to right. I saw an old posting for a 96 that said the wire pairing should be 1& 4, 2& 5, and 3& 6. If this pairing is correct for the 98 as well? Also, if the problem is unchanged, would the next logical step be to change the ignition coil for those cylinders?
