Those codes are all misfire codes. you have misfires in cyl 3 and 6. the 300 means multiple cylinder misfire. Id first start by checking your coils plugs and wires.

I have a 2007 ford taurus with p0300-p0303, p0306, p0316, p2195 and p2196. engine doesnt start anymore but battery is fine.


The old give me money for nothing statement from a mechanic instead of knowing how to fix it.
code p0300 refers to random/ multiple cylinder/s misfire detected===causes--spark plug/s---HT lead/s---injector/s---ignition coil/s--low compression--wiring
code po303 refers to cylinder 3 misfire detected--- engine mechanical fault---wiring---ignition/ fuel system---injector --ECT/MAF sensor --- ECM
code p0306 refers to cylinder 6 misfire detected===causes --engine mechanical fault---wiring---ignition / fuel system---injector ---ECT/MAF sensor---ECM
code po316 refers to misfire detected during start up--first 1000 revs==causes--engine mechanical fault---wiring---ignition /fuel system---injector
code po2195 refers to heated oxygen sensor (HO2S) 1 bank 1 signal stuck lean===cayses ---HO2S---fuel pressure---injectors---intake leak
it also refers to O2S sensor 1 bank 1 same causes and also refers to HO2S 1 bank 1 implausible signal===causes --- short to positive---short to ground---Ho2S ---ECM
code po2196 refers to the same items as 2195 . some causes are also air intake restricted
Have a compression test done some where else and it will indicate the condition of the motor. The rest is sensors and wiring problems.
