Po300 random/ multiple cylinder misfire
p0o36 o2 sensor bad
SOURCE: I would like to know the Location of the P0036 on
P0036....HO2S Heater Control Circuit (Bank 1
Sensor 2)
location is Bank 1 is on the side of number 1 cylinder. Sensor 1 is on the exhaust
manifold. i would change the oxygen sensor on the exhaust manifold i believe thats the one closes to the front of the car with the hood up. good luck
SOURCE: 04 aveo has codes PO300
You don't try anything
The Codes you get are sensors reporting
an out of range condition.
That means you find out why,not change them
The 300 is a misfire issue
I suggest as much as i like to see you
do all your own work,that you go to a repair
shop, that know the technolgy ,and you will not
have any of the test equip needed to solve much
of anything on todays vehicles

P0300 is multiple cylinder misfire, meaning a engine miss is detected on more then 1 cylinder, I would have the codes scanned at auto part store to know for sure which cylinders are actually missing, if there are 2 cylinders that are missing and they are side by side, such as cyl. 1,3. Or 3,5. If so its possible u have a blown head gasket blowing in between the 2 cylinders.. 1st double check that your wires are installed correctly, the coil packs have numbers on them to assure proper location.. Note the rear head has cylinder 1 3 and 5. Some people get that confused.. Providing you have a 3.3, 3.8 or 3.1 liter engine.
make sure the distributor rotation is check
