300 is random misfire and 306 is cylinder #6, I would check the coil pack on #6. If it has separate coils per cyliner, swap the coil, see if the misfire goes to that cylinder. If it does replace the coil.
If it has three coil packs you can still swap the coils. If that doesn't fix your problem, then you will have to check the injector with an ohm meter. resistance between the prongs should be between 11 to 15 ohms. check another injector and they should be relatively close. Let me know
Good luck

I have check engine code P1354 variable valve timing system bank 2 for my 2000 Lexus RX300. Where is this located?


YES, you have to investigate what is throwing your valve timing off. That could be anything from a vacuum leak to clogged injectors, bad plugs, sensor ect. Have the car analyzed to find the cause. There can be many causes. Good luck

2003 acura tl error codes po301 po302 po304 po306 p1399 po300


PO300 and P1399 are random cylinder misfire detected.
PO301 cylinder 1 misfire
PO302 cylinder 2 misfire
PO304 cylinder 4 misfire
PO306 cylinder 6 misfire
I would say that you have damage to the ignition wiring harness or you ECM is failing.

Multiple engine codes PO300, PO303, PO306. what is going bad on this 2005 kia sorento?


I've had similar issues. The fix I used was to take my vehicle to AAMCO and let them run a diagnostic check. Most often it will be at little or no cost and, if you don't want to mess with the fix anymore, they can fix it onsite.

What's your problem? my 2004 mercury monterey has eight codes ,po301,poo53,po106,po316,po300,po304,po305,and po306


PO 300 is multiple misfires detected
PO 301, 304, 305, 306 are misfires in cylinders 1,4,5,&6
PO 053 is HO2S Bank 1 Sensor 1 Heater Resistance
PO 106 is MAP/BARO CKT Range / Perf
PO 316 is Misfire detected 1st 1000 Revs.

On a misfire, I usually push towards the spark plugs, plug wires, and coil packs / distributor coil.
You have PO 106 and PO 053 that need to be inquired about at nearest AutoZone.
They can give you an idea as to what is the problem on these.

Did a MAP sensor **** out and cause all the misfires ?
Did a misfire cause the MAP sensor error?
You see what I'm saying ?...Something caused all the misfires...thinking MAP...but not that familiar with the function of the MAP.

Hope this helps...

Trouble codes for saturn ls2 car is showing the following trouble codes. po300, po306, po451 p2bo3 and c112b


P0300 Multiple Cylinder Misfire Detected

P0306 Cylinder 6 Misfire Detected

P0451 EVAP Pressure Sensor Range/Performance

I have no idea what those last two are. Typo, maybe?

Your first two codes could be caused by old spark plugs and/or leaking plug wires.

Your EVAP code could be a bad fuel tank pressure sensor or a malfunctioning EVAP system. With that code, if you remove your fuel cap and get a whoosing sound, then it is an issue with your EVAP system not properly venting the tank. If you don't get that sound, then the tank pressure sensor is bad.
