in the USA, our cars are OBD2 , (you there?)
and all scan tools can scan this car. an $9 tool (fleabay)
scan it .
or get it scanned, then post the DTC codes. all of them.
if its EVAP , code, tighten the gas cap, reset the PCM (same tool)
and that is not corrected.
you can get the zone to scan it but they 1/2 the time miss them all
and miss factory codes.
buy the tool, or go to any USA ASE certified, shop. and its bees-knees.
multiple code issue (evaporative, catalyst efficiency, and miss fire)doubtfull all 1 source of error but draw attention to the miss fire code PO300 is a random cylinder miss fire, possible crank position or cam position sensors.but i would check timing first.
p0300 is a random multiple misfire, could just need a tune up. you should have the mass airflow sensor cleaned, the p0171 is showing incorrect fuel mixture, best to have the vehicle scanned at a shop so the exact issue can be pinpointed
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.
the flashing light is telling you the engine is miss firing, not that there is fuel in the exhust a miss fire is the only thing that will cause the light o flash the P0300 is a random misfire so i cant tell you witch cylinder but replace the coils that should take care of it....good luck
If you continue to drive it the computer will eventually sort out exactly which cyl is misfiring then list another code showing the cyl that is missing. Otherwise have a competent repair shop with a good scan tool run the car with their scanner hooked up and they should be able to locate the cyl that is missing and what it needs.
