I have an '01 Sable that posted a Check Engine light and the problem turned out to be a Mass Airflow Sensor.

3. Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
4. Incorrect Fuel Pressure
5. EGR system concerns: leaking EGR valve or restricted ports
6.Base engine concerns: low compression, valve train problems and timing issues
7. Ignition system concerns including, but not limited to:
Faulty spark plugs

My mercury sable 2002 motor Ustyle idals bad code p0316,301,303 come up changed spark plugs and wires still showing same codes what should i check now


PO301 & PO 303 are cylinder misfire in the cyclinders
indicated by the codes last number #1 & #3

Spark Plugs get replaced every 3 years or so & have
nothing to do with resolving any misfire issues, unless
they were in the motor for 80,000 miles & worn out

Spark Plug wire easily last 12 to 15 years or more &
usually only fail because they are mishanded & too often

You problem IF the codes are correct & they are not all the
time,is a bad ignition module or individual coil if that is
what you have

Misfire in cylinder 6. chaned coils an spark plugs still come up as misfire in cylinder 6. CHANGED ignition coil still comes up. What should i do next?


Plugs get changed at 70,000 miles
I would suggest that you use the OEM
Plugs,they are made by NGK and are special
on my 2004 LS,I don't know about yours.

Clean the MAF Sensor with the CRC Product
for that

Change the 2 front O2 Sensors at 100,000 miles

Check fuel pressure at the fuel rail on engine

The coil you replaced on #6 ,even though you
have a PO306 Code,doesn't mean that was the
bad one. It is a COP Coil or Ford thing, you will
learn as you get involved with them

In some cases, you buy 1 new coil and walk it
from one cylinder to the next.

On single coil codes, you may get lucky,on multiple
codes or a really bad coil you won't

Your not using any fancy test equipment and
unfortunately a lot of repair shops have it and
don't know how to use it,including dealers

V6 or V8 ?

#2 clyinder not firing in a 02 eldorado with 19000 miles on the car


There are several possibilities.
Based on the year (2002) and low miles (19,000) it probably has the original Plugs, Wires and Coil. Rubber insulation on Wires does dry rot over a period of time. Spark Plugs should be changed about every 3 to 4 years regardless of miles. Wires should be replaced every other Spark Plug change. Translated you should be on you 3rd set of Spark Plugs and 2nd set of wires.
When working in the engine compartment and with the electrical system remember: ther is 40,000 to 75,000 volts present. Bad Wires could mean an electrical shock!
You can cheaply purchase Ignition (Spark Plug/Wire/Coil) Test Kits at most auto parts stores or even at Harbor Freight.
1) Remove the #2 Wire connection to the #2 Coil position.
2) Insert the tester into the #2 Coil position. Clipping the other end onto the engine block or onto a good ground.
3) Start the Engine.
4) You will be looking for a good strong (blue) and rhythmic spark. If it is not strong (yellow or orange) nor rhythmic, the Coil is malfunctioning and should be replaced.
5) If it is a good rhythmic spark, Turn OFF the Engine.
6) Disconnect the Tester and reconnect the #2 Wire to the #2 Coil position.
7) Disconnect the #2 Wire from the #2 Spark Plug.
8) Connect the Tester into the end of the #2 Wire. Clipping the other end to the engine block or a good ground.
9) Start the Engine.
10) Again you are looking for a strong (blue) and rhythmic spark. If is not strong (yellow or orage) and rhythmic, the Wire is bad and should be replaced. Wires should always be changed as a Set is the standard rule.
11) If it is a good rhythmic spark, Turn OFF the Engine.
12) Remove the #2 Spark Plug out of the engine.
13) Check the Igntion end of the Plug for carbon, dirt, or being fouled. Check the Gap.
14) Insert the #2 Spark Plug back into the #2 Wire.
15) Using the Spark Plug Tester. Connect the Tester to the #2 and clip the other end to the engine block or a good ground.
16) Start the Engine.
17) Once again you should be checking for a strong (blue) and rhythmic spark. If it is not strong (yellow or orange) nor rhythmic, the Spark Plug could be malfunctioning.
18) Clean the #2 Spark Plug.
19) Regap the #2 Spark Plug.
20) Retest the Spark Plug.
21) If there is now a strong (blue) and rhythmic spark, then the #2 Spark Plug is now good.
22) If there is not a strong (yellow or orange) nor rhythmic spark the #2 Spark Plug is malfunctioning and needs to be replaced. Again the standard rule is to replace the Spark Plugs as a set.

The several other possibilities relate to sensors. However without additional error codes or the check engine light on, we will assume that the problem can be solved with the solution above.

2002 Sable LS 43,000 miles. Check Engine light on again!


without a fault code its impossible to diagnose. try pep boys or aamco or auto zone they will pull the code for you, usually for free. The code will relate to a sensor or area to be fixed. This will save you money and needless parts . post the code or codes so we can help

Which ignition coil is bad?


I went thru this on my 2002 LS as well.
I replaced one ignition coil at the dealer - only to get the same misfire code on another cylinder. After a little research found out is actuall a gasket/o-ring problem design of the block. Spark plugs are deep in the block - under the oil - which is why they are supposed to last 100,000 miles. But the o-rings start to leak some where between 65k-85k miles. Coils go bad because of oil contamination. If you don't solve leaking oil problem will have to replace coils again - but sooner - because leaking oil will be progressively worse.
Cost - 8 ignition coils
set of spark plugs (who knew they were that expensive
and a ton of cash for the labor to tear down the top of the motor
