P0305- Help! 99 Es300 in 92 - 06 Lexus ES250/300/330 Posted January 3, 2008 Hi there, It's got 84K, CEL on, and sometimes blinking. Autozone says P0305 cyl 5 misfire. I've replaced the plugs with ngk iridiums Replaced fuel filter Swaped coil packs - and cleared codes - stayed with the same cyl 5 Tested voltages to the coil pack- all are in spec. Thinking its the injector? How hard are they to replace? Do I need to take the intake off to get to the rear rail? Thanks so much in advance for any help. Marc

Hi there,

I've replaced the plugs with ngk iridiums
Replaced fuel filter
Swaped coil packs - and cleared codes - stayed with the same cyl 5
Tested voltages to the coil pack- all are in spec.
Thinking its the injector? How hard are they to replace? Do I need to take the intake off to get to the rear rail?
Thanks so much in advance for any help.
