Misfire can be caused by worn out spark plugs, bad ignition wiring, sticking fuel injectors, anything that prevents the cylinders from firing correctly. Good luck!

Replace coil packs on the ford explorer 2006


What codes P0304 & P0308 ? This just means the PCM detected a misfire on those cylinders .an could be a few different things !
What ignition type does your vehicle have coil on plug or a coil pack with 8 plug wire towers ? If you have coil on plug ignition there are two wires going to the coils , one has battery + an the other is control from PCM . Check power first with volt meter or test light . Or use a spark tester on those two cylinders . No Spark Testing control testing

Missing,viborating


Misfire could be a number of things:
a) spark plugs - change them if used over 15K miles - inspect/regap.
b) spark plug wires - change them if over 15K miles - inspect
c) ECM (electronic control module) - test with HEI (high energy ignition) tester.

The vibrating tells me that the engine is running on less than its normal compliment of cylinders - the shaking is produced by the imbalance caused in the engine by one (or more) cylinder(s)
not firing at all.

The "Check Engine" light probably is coming on due the the misfire condition. Go to Pep Boys or
Advance Auto Pats, where they'll tell you (free) your codes causing the "Check Engine' light to be
lit - the code coming from your truck's computer will probably be one or more of:
P0300 - Random/Multiple Cylinder misfire detected
P0301 - Cylinder 1 misfire detected
P0302 - Cylinder 2 misfire detected
P0303 - Cylinder 3 misfire detected
P0304 - Cylinder 4 misfire detected
P0305 - Cylinder 5 misfire detected
P0306 - Cylinder 6 misfire detected
P0307 - Cylinder 7 misfire detected
P0308 - Cylinder 8 misfire detected
P0313 - Misfire detected with low fuel

Engine light just came on took to auto zone they gave me this code PO304 Trying to see what it is


A P0304 OBD2 code is "cylinder #4 misfire detected". The first place to start is your spark plugs. 1. Check condition and for wear. 2. check the spark plug wires or coil packs(depending on which you have).

Where is #2 cylinder on 2000 jaguar s type 4.0?And what is code p0302


I recently starting having this problem also (only code p0305/308). That code means "miss-fire" on #2 cylinder. The #2 cylinder is the nearest cylinder on the right (closest to front of car on drivers side) if you are standing in the front of the car.
