do a compression test. cylinder 3 could have a bad valve lifter or valve.kia sephia dont have push rods.it have a bucket type followers.a intake leak to that cylinder can also cause misfire problems.

This could be any number of problems in your spark system but most likely your control module for your spark plug coils.

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.

Is there an erg valve on a honda accord 2008 4 cyl


code p0300 refers to--random/multiple cylinder/s misfire detected...Causes---spark plugs---HT leads---injectors---ignition coils ---low compression ---wiring
code p0302 refers to cylinder 2 misfire detected Causes ---engine mechanical fault---wiring---ignition/fuel system ---ECT/MAF sensors ECM
code po303 refers to cylinder 3 misfire detected Causes Engine mechanical fault---wiring---ignition/ fuel system ---injector---ECT/MAF sensor ECM The common fault to all is the fuel/system ignition
I would have the injectors checked and have a pressure test done on the fuel manifold to check pump and fuel regulator valve.

Kia rio 2003 errorcodes 1166,102,1505 1507,300 found on the scan what is the reason


Hi there:P1166 - HO2S11 Heater Circuit Fault (Bank 1 Sensor 1)


P0102 - Mass Air Flow (MAF) Circuit Low Input

A code P0102 may mean that one or more of the following has happened:

  • The MAF may be disconnected, or a wiring connection may be bad
  • The MAF may be dirty or otherwise contaminated (Note: if you use a reusable oiled air filter, be careful not to apply too much oil or that can contaminate the MAF).
  • The MAF sensor may be faulty
  • The vehicle computer may be faulty (very rare)

Possible Solutions

The simplest thing to do is to reset the code and see if it comes back. Then start with the cheapest, easiest repair procedures:

  • Verify that the Mass Air Flow Sensor wiring is connected properly and that there are no broken / frayed wires.
  • Inspect for any air leaks near the MAF sensor.
  • Take the MAF out and clean it using a spray cleaner such as brake cleaner or electrical contact cleaner. Be gentle with the sensor.
  • Check the voltage of the MAF sensor (refer to a repair manual for vehicle specific information)
  • Replace the MAF sensor.

P0300 - Random/Multiple Cylinder Misfire Detected
A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.


A code P0300 may mean that one or more of the following has happened:
  • Faulty spark plugs or wires
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector(s)
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Stuck/blocked EGR valve / passages
  • Faulty camshaft position sensor
  • Defective computer
  • If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable).
Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.



Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Check engine light flashes when accelerating or decelerating, code P0300, NO POWER IN HIGHER GEARS, or uphill or at high altitude Above 7000 ft.(truck is six speed manual)


P0300 = random and multiple misfires. Check your coils and ignition electrics - this is where the fault would appear to be by the OBD fault code displayed. Hope this is of help - good luck.
