    thanks don. the hesitation is caused by my acceleration above 60 mph. My truck increases in speed, but around 60 mph it starts to sputter and then jerks.

Wow! So many things can cause hesitation or miss. Did you run the OBD II scan? Auto-Zone will scan it for you. Usually on an older car,unless the spark plug wiring has been recently replaced,you need to do that too.
Then you have a lot of age on the coil pack also.Also clean your MAF sensor and your idle air control valve at the throttle gizmo.
Describe the hesitation a little more. don-ohio (:^)

My 2008 ford explorer engine hesitates what do I do


First make sure check engine light not on. Second check spark plugs condition plus make sure all ignition coils are firing. Third check fuel pressure. If all pass try upgrading gasoline octane. GOOD LUCK.

My 1998 ford exoedition check engine light is on and the code is cylinder 5 missfire


A P0305 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #5.

Symptoms may include:
* the engine may be harder to start
* the engine may stumble / stumble, and/or hesitate
* other symptoms may also be present

Causes: A code P0305 may mean that one or more of the following has happened:
* Faulty spark plug or wire
* Faulty coil (pack)
* Faulty oxygen sensor(s)
* Faulty fuel injector
* Burned exhaust valve
* Faulty catalytic converter(s)
* Running out of fuel
* Poor compression
* Defective computer

Possible Solutions:
* If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

* If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Hope this helps.

Engine light is on, flashes when driving above 100 Km


stop by local parts store (Autozone,Advance, etc) and have them do a free fault code test. They can print out a list of faults and clear the codes

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.

Firing Order diagram for 2006 Ford Explorer


Hope this helps. The ignition coil:
  • changes low-voltage pulses from the PCM to high-voltage pulses.
  • fires 2 spark plugs simultaneously.
  • has 3 transformers.
    • One transformer fires the spark plugs for cylinders 1 and 5
    • One transformer fires the spark plugs for cylinders 2 and 6
    • One transformer fires the spark plugs for cylinders 3 and 4
Spark plug wires:
  • carry high-voltage pulses from the ignition coil to the spark plugs.
The spark plugs:
  • change high-voltage pulses to spark at the gap, which ignites the fuel and air mixture.
The firing order is 1-4-2-5-3-6.

My 2003 ford expedition reads a code 0303= 3 cylinder misfire, which side of my vehicle would that be on and could replacing ignition coil and spark plug fix it and stop the lose of power and hesitation?


Third cylinder back on the passenger side. I'd recommend changing all 8 coils and spark plugs. These coils don't last long, and once one goes, more will fail soon after. This job also requires removing the fuel rail to gain access to the coil and plugs. I personally have the same SUV and went through the same issue!!

1996 Ford Explorer vibrates when idling. Also have noticed that when I go 80 mph, it "jumps" every few seconds. Like it skips a beat. I don't know how to explain it but it seams to "stall" like if you were...


You have a hesitation. A hesitation is cause be either:
1. bad spark plug
2. bad spark plug wire
3. bad or leaky or plugged injector
4. timing is off
5. leaky vacuum hose
