If the other coils are functioning, then voltage to the coil pack is ok. removing the spark plug wire from the suspected bad coil with no change in engine performance is a reliable procedure to check for a bad coil.

How to do a spark plug change on a 2003 Jeep Liberty


how to move hands, ?
what tools
im i to guess this is your first spark plug pull even on a lawn-mower?

what engine do you have, 90% posts lack what engine it is on a engine question, and we are still guessing, and nuttn happens.
lets see.you pull HV wires 1 by 1, and replace them using a spark plug socket wrench.
if the engine has COP coils, those come off, first, (do tell got cops)>?

do not mix up the spark wires or it will not run.
why not watch youtube of 10000 doing this on all engines. to get a fell of the ways and means.... simple huh?
only start a spark plug by hand , never use a wrench.
rule1. end.
do not over tighten them (rule 2)

2.4L engine, 4 cylinder??????
this is my guess.
JEEP KJ
ill look that up for you.
ok i looked, the 2.4L uses coil pack
so rule 1 applies, DO NOT MIX the HV wires on the COIL PACK>
remove the spark plug wire from ONE spark plug]
remove the spark plug (turns counter clock wise)
put in new plug (right part number and gap it to spec.
torque it to spec, and put back the wire.
move to next plug wire and repeat.
success.

HV means those high voltage spark wires, that make you glow like a June bug if you get HIT. the 50,000 volt wires.

RE14MCC5 (Champion #) plugs
48 thou gap
but the hood sticker wins this ... not me.... read it.

the 3.7 has 6 cop coils , no signal coil pack.
my 3.8L has coil packs.
so as you can see , each engine is unique, by year and car.

I have a 98 4runner with 300000 miles. It's been running excellent but day before yesterday it started sputtering like a tractor when driving and idoling. Service engine light blinks when in overdrive, and...


First check the plugs. Pull the #6 plug and look at the electrode. If it's wet and/or dark (black) it's probably not firing correctly. What is the spark plug gap? Is the center electrode eroded (not flat on the end)? Swap in another plug and see if it makes any difference. How old are the plugs?

Second, check the wires. Did you replace the wire(s) when you changed the coil pack? They should be replaced periodically (I replace the wires on my '96 4Runner at about 100k miles). Check the wires with an ohmeter. Resistance should be around 16-17.5k ohms (depends on length).

FYI, each coil pack on your vehicle fires two spark plugs. The #6 spark plug is fired by the #3 cylinder coil pack, so if the coil pack were bad, most likely both the #3 and the #6 plugs would not fire.

Daewoo tacuma Just changed my spark plugs and HT leads now enging runs rough and stalls on idle


CHECK YOU FIRING ORDER, YOU MIXED THE IGNITION WIRES, IF IT IS A 4 CYL, FIRST CYLINDER #1 IS NEAR THE BELTS, CHECK COIL WIRES FOR NUMBERS, OR DISTRIBUTOR CAP FOR CYLINDER NUMBER OR COIL PACK FOR CYL #, AND FOLLOW THE WIRES TO THE SPARK PLUGS. MAKE SURE THEY ARE RIGHT, NEXT TIME DO ONE PLUG AND ONE WIRE AT THE TIME.

Rough idle, Check engine 0306


We had the same problem, on the coil insert #6 it is not the spark plug in firing order #6 it is the number 6 near the firewall actual coil insert that is causing your problem. We changed ours and the thing is running fine now. ebay it, unless you have between 50-100 dollars to waste. Ours cost 25 dollars on eBay. Ours was a 2002.

Changed plugs and wires and put on a new igntition coil and it is stillmissing on 2 cylinders


I believe the Mustang has 3 coils for a V6, and 4 for a V8, each coil controlling two cylinders. First you need to check and find which two plugs are misfiring, and if they go to the same plugs. It may be that more than one coil is defective and the coil pack needs replacing. With the vehicle running pull one spark plug wire at a time to find the missing cylinders. If the engine slows or starts running rough, that cylinder is firing, if you pull the wire and there is no change you have found your missing cylinder, from there trace the wire back to see which coil it plugs into. Also, make sure your plug wires are not touching each other and are in the spacers the factory installed. If you still can not find the problem it may be in the main computer. Most autoparts will run a diagnostic check for free.

Ok i recently changed spark plugs on my 1994 buick skylark. when i was done changing plugs i started car up and smelled strong exhaust smell. so i checked the plugs wires and found out that when i pulled...


Did you mean coil the 1994 3.1 did not use a distributor , sounds like a bad coil pack and cylinders #3 and #6 do use the same coil. I would also check 3 and 6 plug wires this system is a waste spark design meaning when # 3 coil fires it is supposed to go through #3 plug wire , through #3 plug ( ground) through the engine block through the #6 plug then through the #6 wire then back to the coil, Then when #6 fires it works the opposite way, so in theory you could have one bad wire affecting 2 cylinders .....

How to change te spark plugs


Hi: If this is your 1st time to Change your Spark Plugs, I recommend that you First of All Get the Correct Spark Plugs from your Auto Parts Store, Then Locate your Spark Plug Wires which run from your Distributor Cap to your Spark Plugs.If you have a V-8 There will be 8 if you Have a V-6 Then You'll have six Spark Plug Wires and 1- COIL Wire which is located in the Center of your Distributor Cap to your Coil. It is the Shortes Wire.I Recommend you ONLY do 1-Spark Plug at a Time, This will Prevent you from getting any of your wires Crossed which will Cause your Engine to Run Rough ,Back Fire or Not even Start,So just Pull off 1-Wire From Spark Plug and one Wire From Your Distributor Cap, You'll Need a Spark Plug Socket Probally 5/8th in. And a Ratchet and 2- Different Size Extensions to beable to reackh all your Spark PlugsNOTE!! Buy you a Spark Plug Wire Tool there not very Expensive but well worth it,This was you Can Pull the Wires with out Damaging Your Wires.And you Might Want to Put NEW Spark Plug Wires On as well, If So and I do Recommend This. And Again Just do 1- Wire and Plug At a Time So you'll know you Have Not Crossed any Wires. Hope This Helps You ,Please Respond by Voting on This Problem And How it Helped You. Thanks From WYOCWBOY

2001 MPV Runs Rough at Idle and Low end Throttle


This could be a bad fuel injector. Lean implies low fuel to the cylinder which will cause a misfire.
