Im New!!! multiple misfires! please help!
I have my 2002 IS300 5 speed
car has been running great %100 stock
recently It started misfiring real bad,
Codes that have come up are as follows
P0301 Cylinder #1 — Misfire Detected
P0302 Cylinder #2 — Misfire Detected
P0303 Cylinder #3 — Misfire Detected
P0304 Cylinder #4 — Misfire Detected
P0305 Cylinder #5 — Misfire Detected
P0306 Cylinder #6 — Misfire Detected
P0300 Random/Multiple Cylinder Misfire Detected
There was also a bank 1 o2 sensor upper CEL as well but i dont remember the code
With that being said i have replaced common items that can cause this.
Sparkplugs with OE NGK Iridium
Sparkplug wires NGK
Coil packs OEM
bank 1 o2 sensor, same denso as OEM
With all this the car still throws the same codes and im at a loss,
When car is cold it will start run just fine until it warms up,
As soon as it warms up all this starts to happen.
Any help on this would be greatly appreciated! Thank you in advance!!
