    misfire 1,3,6 cylinders. The engine light comes on and off. The coils were replaced. I have been doing some research online and suggested to my mechanic that perhaps the crankshaft sensors might be the problem. IS dis module the same as the crankshaft sensors?

Have you tried replacing the ignition coils? If they get old and stop working, or if they're damaged, they won't send a strong enough spark to the plugs. AutoZone (I think) apparently does free diagnostic codes for a check engine light. I don't know if you have a check engine light on or not, but maybe the light burned out? It might be worth a try to call them and ask if they can check the codes for you for free.

Chevy s10 2002 p0302, p0457


code p0302 refers to cylinder 2 misfire detected===causes --engine mechanical fault--wiring---ignition/fuel system---injector--ECT/MAF sensor---ECM
code p0457 refers to evaporative emission system--leak detected (fuel cap loose/off) ==causes --mechanical fault--hose connections---EVAP pressure sensor
Replace faulty items. Use only genuine items as replacement
as non-genuine are not always compatible with the OEM fitted CPU units. This results in the fault codes not cancelling out. If possible you may be able to get the CPU reset to work with the non genuine items you already have.

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.

Cylinders 1 and 3 misfiring on 2.4 Liter 97 chevy malibu


code p 0300 is random/ multiple cylinders ----misfires detected ===causes ---spark plugs ---HT lead/s---injector/s---ignition coil/s---low compression---wiring
he has changed a lot for nothing
a 5 year old engine can have a lot wrong with it --so new out of a crate is no guarantee
most misfires are from injector problems
it could be a loose valve seat insert so have a compression test done if moving the injectors to new locations doesn't move the misfire

P0308 cylinder 8 misfire detected? How to repair?


Fuel injector cleaner commonly has a low success rate, and will not help if it's more than one cylinder that is missfiring. The fact that you have a "rattle" noise, leads me to beleive the engine is not receiving fuel on one or more cylidners. If it is all the cylinders, than the fuel pump may be the culprit, or the fuel pump circuit. But if only one cylidner is missfiring than it is a possibly an injector. A code P0300 refers to all cylinder missfires, and any code between P0301-P0308 distinugiushes a particular cylinder.

Misfiring
1- a general electrical tune-up (spark plugs, wire set, cap & rotor) is a basic start to cure this issue. Wiggle the dist shaft while you are in there, if you have one.
2- Then a good carbon cleaning / throttle-body cleaning.
3- Vacuum leaks at any of the hoses that connect to the Intake manifold; especially the MAP sensor connection.
4- If that does not help then the O2 sensor could be bad or drifting.
5- Funky coil/coil-packs
6- Theoretically a microsecond glitch in either the cam or crank shaft sensors would cause this, but I am not aware of this as a typical cause.
7- Lastly a funky PCM but again it is not common for this to cause miss-firing.

Note for the V8 then also:
a) bad erg valve (this dilutes the combustion gases and hence raises the combustion temp
b) a leaky plenum/Intake manifold gasket. Leaking Intake gasket symptoms

Also can check the TSB 18-48-98 Ignition System Cross Fire/Secondary Ignition Wire Induction (Complete Version )

Hope help with this (remember rated this). Good luck and have a nice day.

99 dodge caravan #4 cylinder misfires, i replaced spark plug wires and spark plugs. Scanner showed #4 still misfiring, could this be the coil?


It could very well be a bad coil pack,or you have low compression in that cylinder.If the compression is good then go with the coil pack,if not you may need a head gasket or an intake manifold gasket.

MISFIRE ON CYLINDER 5. I have changed plugs, wires, coil pack, fuel injector, and ECU unit. I have had two compression tests and it was put on a diagnostic machine. Everyone is scratching their heads as...


Same problem. 94 LHS 3.5L engine. Noticeable rythmic misfire at idle. Looks like cyl 5. When I pull the injector connector off of cyl 5 the idle rythm does not change. It does if i pull the inj connector off of any other cylinder. Spark OK. Injector ok using seperate 12vdc supply (clicks). Connector to injector has pulses on it verified with a test light. Inj coil resistanceis 12 ohms, exactly what it should be.

Still need to check compression and intake manifold gasket
