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.

Have a 2002 Chevy Silverado 5.3 4wd. having engin hesitation problems.... service engine light came on...... Changed plugs (Autolite .040 gap) and wires. Problem continued, got worse Had auto parts...


Try swapping the injector on that cylinder with the one next to it and see if the misfire changes to the other cylinder.If it does then you have a plugged or bad injector.It it still stays on that same cylinder then check compression on the number 6 cylinder.Let me know what you find out.Good luck.

ENGINE LIGHT FLASHING...CAR MISFIRING...INSTALLED NEW PLUGS...WIRES...IGNITION COIL PACK....INJECTORS


the flashing light indicates to the driver that the engine is under severe misfire wich could lead to damaging the cat. Have the codes pulled by autozone or advance they do it for free. Then start there but it sounds like it could be your oxygen sensor

2002 Hyundia Elantra Service engine soon light.


When the check engine light flashes, It's not giving out codes. It is telling you that the engine is misfiring on 1 or more cylinders. New plugs and wires might fix your problem.

2003 Silverado rough idle, idles good after "check engine" light


Check your o2 sensor voltage, those trucks are real bad for o2 sensors, and yes if one sensor is reading 0mv, the others will start to drop out, and the vehicle will run very, rough. You also may check fuel system pressure, should be almost 60p.s.i. If its alot lower, Id be looking into a fuel pump. If that vehicle is drive-by-wire (no throttle cable), the throttle bodies get very dirty and cause that concern also. Id start by having the vehicle scantested.
