It can be a sparkplug or wire. If not attended to it can destroy the O2 sensor which is very expensive

My 03 kia sorento is misfiring at 3 and 4.... is this just my spark plugs or is this the coil pack as well


Could be either, you have 1 coil for each cylinder (6 total). The problem is #3 is the rear middle cylinder. You have to remove intake plenum to gain access to rear bank. #4 is front center. What you can do, is swap #4 coil with the one next to it and see if the misfire migrates to that cylinder, then you know it's a coil problem. If you do have to remove plenum, you should replace rear plugs at the same time.

I have a cylinder 6 misfire on my 00 cadillac deville. do u think the plugs need to ne replaced?


Usually, if you only have 1 cylinder misfiring, you have either a bad spark plug or bad spark plug wire. If you replace the cylinder 6 spark plug and still have a misfire condition, replace your spark plug wires. If replacing the plug and wires doesn't fix the problem, replace the ignition coil.

2002 ford escape 3.0L DTC P0305and P0306 what would you ck


P0305 - Cylinder 5 Misfire Detected
P0306 - Cylinder 6 Misfire Detected

When a misfire occurs, engine speed will fluctuate. If the engine speed fluctuates enough to cause the Crankshaft Position (CKP) sensor signal to vary, The Powertrain Control Module (PCM) or Electronic Control Module (ECM) can determine that a misfire is occurring.

When is the code detected?
- Engine Cylinder #5 and #6 is Misfiring.

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/loss of power
- Hard start
- Engine hesitation

Possible Causes:
- Improper spark plug at cylinder #5 and #6
- Insufficient compression at cylinder #5 and #6
- Incorrect fuel pressure
- The injector circuit is open or shorted at cylinder #5 and #6
- Fuel injector #5 and #6 may be faulty
- Intake air leak at cyli

Possible Solution:
- Perform Injector Service
- Replaced Spark Plug #5 and #6
- Replaced Injector #5 and #6
- Replaced Ignition Coil #5 and #6

Hope helps.
