How To Install Replace Ignition Coil 91-10 Ford V6 3.0L 4.0L 4.2L 1AAuto.com

[awaldegrave]

I have a 2004 ford ranger V6 85,000 km

Should I change the coil,

I don't know how many miles this part is good for.

@awaldegrave I would leave it on there until it starts to cause a problem. You should change the spark plugs at the manufacturers recommended intervals.

changed plugs,wires,and coil pack engine light still on with code p0300

[1aauto]

@dwt56 That code may point to a multiple cylinder misfire. If you have other codes behind it, they should pinpoint what cylinder may be causing the issue. You could try to clear out the code and see if it comes back after 3-4 heat cycles.

[dwt56]

@1aauto the codes say po300 mostly and random other cylinders misfireing. I was wondering if my 2004 4.0 has a camshaft synchronizer ....I here a chirp coming from under the hood sounds like a cricket. One thread I read says that the SOHC 4.0 does not have the synchronizer...I am a machinist not a car mechanic so I am lost on this type of system.

@dwt56 You could try to replace the spark plugs if they have been in there for a while and also the coil. It may be the coil that's acting up. Hope this helps you out.

@chengg did you get your truck fixed? mine does the same thing at about 17 miles get misfire code and at times truck misfires. It all started after replacing seperated crankshaft pulley. I have replaced wires ,plugs and coil pack..still does it. Crankshaft sensor appears to be ok. Help!!

[1aauto]

@dwt56 Have you tried to pull any codes from the vehicle to see what they may pointing to? If you have some, it should tell you what the issue is and help to point you in a direction.

Hi I have a '99 Ford Explorer and I have just ran the code reader, it says misfire on cylinder #2 along with P0171 and P0174 which are basically fuel system running too lean on both Bank 1 and Bank 2. Could those be due to a defective coil? Please advise...

[1aauto]

@chengg02 I would repair the misfiring cylinder issue first and then see if it clears the bank codes. If it does not it could be a couple of bad 02 sensors.

[chengg02]

@1aauto Do you mean to replace the coils to repair the misfiring cylinder issue? I have done that, 17 miles later, p0171 and coil #2 misfire came up again... took a little longer than usual (before replacing the coils the codes would come up quicker). Any ideas??

[1aauto]

@chengg02 If the codes point to a bad O2 sensor then I would also replace them to see if that helps to clear things up. It might help the issue out.

is this video the same procedure for 2001 f150. code po303 missfire on 3 ,bad coil? very rough.love your videos

[1aauto]

@reddog9401 If it has a V6 in it, it should be the same or similar to the one that we have shown in the video. Hope this helps you out.

I just replaced the ignition coil on my 99 Explorer last night, and as soon as I cranked up the truck, It still idled rough and it smelled like sulphur. I'm pretty sure it's the catalytic converter, but do you have any suggestions on how the ignition coil might have caused the problem?

[1aauto]

@ecuplanr You may want to check around where you were working to see if something else may have been disturbed that's causing the issue. Possibly a disconnected wire, or bad wire.

I am having trouble with my 92 f-150 ford. It would start but later on when i turn it off. It would not turn back on. I don't know if it is the ignition module, i took it to many mechanics but they tell me it one thing and they supposedly they fix it and later on in a couple of days. it would do the same, i already change the gas pumps and the coil and i still have the same problem. i am not good with cars and i need some advice.

[1aauto]

@peacehippie32 If it happens more when it's damp out it could be a coil. You may want to get a spray bottle with water in it and spray the coil while the vehicle is running to see if it's arching out anywhere.

Thanks, man!

[MsRealamerican]

thank you very much. you make it a lot easier for us that cant afford a mechanic to do it ourselves

Same thing happened to me just a few minutes ago. Car started shaking and missing really bad while driving (been raining for days) with a check engine light that went away after about 2 minutes. I got it home, let it sit and started it back up and it isnt doing it. It has been acting funny for a few weeks now. Bad coil?

[1aauto]

@FastisFast I would have the code run on the check engine light, and I bet that will tell you what's causing the issue.

[1aauto]

@FastisFast I would have the code read on the check engine light. More than likely that will tell you what's causing the issue.

[22bradsutter]

will a bad coil make the car shake as you are goin down the raod and make your check engine light turn on???

[1aauto]

@22bradsutter A bad coil will cause misfiring which can cause the vehicle to shake and a malfunctioning coil will usually turn on a check engine light. There can be other causes though.
