I started having a problem about a month ago. My 2003 Mercury Grand marquis LSE tuned up at 100k currently 145k. started hesitating and slight bucking at cruise speed. I went to autozone and coded #8...

A misfire can be related to a number of causes. Since the coil and spark plug were replaced and it did not solve this issue, it is most likely related to the circuit for the number 8 cylinder. A thorough inspection of the electrical circuit is what is required next. Also, engine compression will need to be tested on that cylinder as well as cylinder number 6 that is next to it. Vacuum leak around the intake port of the number 8 cylinder could also be a cause and will need to be checked.

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.

- 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.

Misfiring. Stopped at AutoZone and computer said #6 cylinder misfiring. Do I just need to change the spark plug or get a new coil pack? Also, which plug is number 6

number 6 plug depends on what engine you have 6 cylinder or an 8 cylinder you need to be careful with that code it could be a plug , a plug wire , a coil pack . i had an issue with that code and it was the crankshaft sensor 38 dollars from an autoparts store dealer wanted 170.00 ! crank sensors have an adjustment on them a few thousands of an inch and yes it makes a difference ! hold it down while you tighten the bolt . hope this helps

4.7l V-8---error code P0308 is being displayed---about a year ago, I replaced the plugs and all 8 coil packs---thanks

Hi. This P0308 code means that the the PCM has detected that one of the engine's cylinders are not firing properly. In this case it will be cylinder Number 8.

A code P0308 may indicate that one or more of the following has occurred:

1 Faulty spark plug or wire
2 Faulty coil (pack)
3 Faulty oxygen sensor(s)
4 Faulty fuel injector
5 Burned exhaust valve
6 Faulty catalytic converter(s)
7 Running out of fuel
8 Poor compression
9 Defective computer

If there are no symptoms, the first thing to do is to reset the code, with a code reader, 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 affected cylinder and plug/coil assembly. 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-COP-). In some cases, the catalytic converter has collapsed. If you smell rotten eggs in the exhaust, your converter may need to be replaced. I've also been told several times that the problem in this case could be a faulty injector at that cylinder 8.

#8 coil pac, cylinder misfire...Need diagram The mechanic says I need a coil pack and spark plug replacement for the #8 ...Need diagram to figure out which one it is. it is

The #8 coil and spark plug are located on the drivers side rear of the engine. You will need a 7mm socket to remove the bolt that holds the coil down. After the bolt is out, pull the coil upwards and remove. Next you will need a 9/16" spark plug socket to remove the spark plug which is located in the hole that the coil came out of. The spark plugs in a 5.4L engine are sometimes frozen into the engine. If it is very hard to turn the plug, try spraying some WD-40 down the hole onto the plug and let it soak in for a while. Do not try to force the plug to turn, it will break and a special plug extractor will be needed to remove it.
Hope this helps you!

I have a ford explorer 99 but it's giving a error code PO306 what do u think it is

It sounds like a misfire. Check spark plugs 5 and 6. It could be bad fuel, bad plug wire, or weak coil. Check the fuel injectors as well. Other possible causes could be an egr valve stuck open, vacuum leaks, low fuel pressure.
