Try to check all the spark plugs if it is functioning well,or try to check for the high tension wires or maybe replace it or try to check if there is a crack inside the distributor cap.or it is late ignition timing.

No spark on cyl 3 and 4


What engine ? 2.2 l or 2.4 L. You don't say if any codes are set. no P0303 - P0304 cylinder's 3 & 4 misfire ? or any other ? No the cam sensor wouldn't cause just two cylinders to misfire. The PCM triggers the ICM to turn on an off coil's to build up an collapse the primary voltage inducing the secondary voltage . This engine is equipped with a non-distributor ignition system called the electronic ignition (EI) system. The primary circuit of the EI system consists of the following components:
?€¢
Two separate ignition coils

?€¢
An electronic ignition control module (ICM)

?€¢
A crankshaft position (CKP) sensor

?€¢
Related connecting wires

?€¢
The ignition control (IC) portion of the powertrain control module (PCM)
Important: The camshaft position (CMP) sensor is only used for a misfire detection. It is not part of the ignition system. !

Misfiring


code p0303 refers to cyl 3 misfire detected ===causes engine mechanical fault--wiring--ignition/fuel system--injector--ECT/MAF sensor--ECM
code p0316 refers to misfire detected during start up --first 1000 revs===causes --engine mechanical fault--wiring--ignition/furl system--injector
the common fault cause is ignition/ fuel system and injectors so I would be checking fuel pressure and injector systems for clean and wiring connections are good especially on no 3 injector.

Po300pd code mean


DTC P0300 indicates random multiple misfires have been detected. Probable causes are:
1. Vacuum leaks, damaged hoses, improper routing
2. Contaminated fuel
3. Ignition system problem(s). Check the ignition module, coil, spark plugs and wires
4. Fuel system problem(s)

Random multiple misfire P0300, P0302, P0304 on 2006 Kia Rio


A competent mechanic will check all probable causes associated with these DTC codes.
Code P0300: Random-Multiple misfire detected. Probable causes:
1. Vacuum leaks, damaged hoses, or improper routing
2. Fuel contamination
3. Ignition system - Ignition module, coil, spark plugs and wires
4. Fuel system
Code P0302: Cylinder 2 misfire detected. Probable causes:
1. Control unit software in need of updating
2. Faulty PCM or ECM
3. Faulty fuel injector
4. Ignition system
5. Fuel system
Code 0304: Cylinder 4 misfire detected. Probable causes:
1. Control unit software in need of updating
2. Faulty PCM or ECM
3. Faulty fuel injector
4. Ignition system
5. Fuel system

Be sure the invoice enumerates all of these probable causes as having been checked. Also, some of the replacement parts installed earlier may be faulty.

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.

What causes an engine misfire?


It depends on whether it is a random or localized misfire. A trouble code P0300 or a combination of several P030x codes is considered random. These are caused by ignition systemic issues, such as loose or bad crank sensor, ignition module, deterioriated ignition wires, coil or rotor, etc. Somethimes they are also caused by fuel/air issues, such as dirty throttle body or clogged EGR system/failed EGT valve.

Localized misfires are on a single cylinder, for example, P0302 would be cylinder 2 misfire. This would be caused by a bad plug, wire, or possibly a burned valve or blown head gasket.

Am I answering your question OK? If not, please feel free to ask more questions.

Chech engine light code OMDII 300 vehicle back fires from stand still till speed 35 to 40 mhp 1998 corolla can you help


OBD II 300 Random/Multiple Cylinder Misfire Detected

When the misfire monitor detects a misfire, it will trigger the check engine light with the specific cylinder number as the last digit in the P030X code. For instance cylinder 1 misfire is P0301, cylinder 2 is P0302 etc. In this case we have either multiple cylinders misfiring, or the computer simply can't determine the specific cylinder, and as such we are left with the P0300 in computer memory.

Possible Causes:

Fuel injectors, related wiring, sensors and computer issues
Running out of gas, or poor fuel quality
Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
Incorrect Fuel Pressure
EGR system concerns: leaking EGR valve or restricted ports
Base engine concerns: low compression, valve train problems and timing issues
Ignition system concerns including, but not limited to:
Faulty spark plugs
Faulty coil or related wiring
Ignition module or related wiring issues
Ignition related sensor faults or wiring issues

Misfire and loss of power?


A bad cat will not cause a misfire, it usually falls victim to a misfiring engine and gets ruined. A misfire is usually caused by bad spark plugs, ignition wires, or distributor cap and rotor. There are other things as well but the ignition system is always the starting point.
