Toyota Repair: 99 solara p0300, o2 sensors, fuel injectors


Question
my solara is throwing multiple cyclinder misfire along with misfire cycl2 and misfire cycl6.  also gives a p0153/p0133.  what does it mean when these codes are on at the same times.  can it be just a coilplug.  the motor runs rough only at idle.  also bogs down after it starts to run rough.  after steady gas and driving it runs fine until i stop at a red light again.  the o2 sensors are new along with a fuel filter and spark plugs.

Answer
First check the spark plugs, this engine uses three coils on the front bank of the engine (bank two) each coil fires two cylinders, cylinders #1+4, 2+5 and 3+6, the coils are on cylinders 2,4,6, so it would make sense that coil #4 is good but keep in mind that a failure of the #2 and #6 coil would also cause a misfire of cylinders #3 and 5 but that's not the case, the other codes are caused by the misfire and can be ignored until the misfire is fixed. Toyota had also issued a service bulletin concerning cylinder misfires, there were some problems with the fuel injectors, if you would like a copy please reply to me at <tedrttr@yahoo.com>
