Testimonial: "I will let you know. The Tundra is 2 hr drive away, will drive to get it, switch rigs and hopefully drive it back to a dealership close to where I work. Dealership hopes that the truck comes back and misfires for them besides checking for the computer code."

  • Erik Aploks Nov 07, 2012

    The shop was able to catch the truck misfiring this time, rather than taking my word for it and looking at the computer's fault code.,last misfire was on #8 before all the ignition coils were change out to new ones. Code today was misfire on #8

  • Erik Aploks Nov 07, 2012

    Fuel injector for #8 seams to be the problem.

You can switch ignition coil to the other cylinder to check if the misfire follows that pack. Or check for ohms.

SOURCE: I have a 1998 toyota sienna with 132,000 miles on

my name is Jerry Tiet. Base on my experience on 1998 Toyota Sienna with the DTC P0303 show there is a misfire in cylinder #3. a possible cause is the ignition coil of the #3 cylinder. Compare the resistance value of the ignition coil of cylinder #3 with the other coil or simply switch ignition coil #3 with one of the other ignition coil and clear the DTC with the scan tool. Then run engine for couple days. If the check engine light on again. Let me know what is the DTC code.

2003 Pontiac Vibe - 4 Cyl. 150k miles. Ignition coils keep going bad - every 4-6k miles. Coil 1 has been replaced 4 times, Coil 3 once. Coil 4 twice in the past year (20k miles). All spark plugs

Install new spark plugs, 4 new coils & replace the oxygen sensors

O2 Sensors are only good for 100,000 miles, then slow
down or quite

No idea why the coils do not last 5 or 6 years

Cylinder #1 is always at the front on a 4 cyl

Go to Rock Auto --Buy Wells Coils,NGK Double
Platinum Plugs & NTK O2 Sensor

Those parts are expensive because you have a Totota
Motor I guess

Clean MAF Sensor with CRC MAF Sensor Cleaner

I cant find spark plugs

I am writing you the method on how to change sparkplugs, you may now have an idea where spark plug is loacted.

The Ford Expedition uses eight spark plugs to accommodateits eight-cylinder engine. Replacing the spark plugs every 75,000 miles is animportant part of overall vehicle maintenance. 1. Disconnectthe negative (black) battery cable from the battery terminal. Remove thewiring harnesses from the spark plug coils. There will be four on each side ofthe engine block, which you can remove by simply pulling them out of the sparkplug coils. 2. Unscrew the 7mm bolt from each of the spark plug coils usinga socket wrench and 7mm socket. 3. Pull each spark plug coil out of the engine block. Pull themout slowly, being careful not to damage or tear the coils. 4. Use a socket wrench and spark plug socket to unscrew eachspark plug from the engine block. Once you remove these, discard them. 5. Place the new spark plugs into the engine block and tightenthem using the socket wrench and spark plug socket. 6. Slide the spark plug coils back into the engine block. 7. Bolt the spark plug coils back into place using a socketwrench and 7mm socket. 8. Reattachthe wiring harnesses to the spark plug coils. 9 . Connect the negative battery cable to the negative batteryterminal.

Just remove an ignition coil that you know is good, with a good spark plug and hook up to the wire were the bad one was. Have someone start your truck up for you and if the spark plug fires then the ignition coil that you took off was bad. But before you do that just try a new spark plug that may be the problem.

Can't find the spark plugs on a 2004 toyota tundra V-8

If the engine is the same as my 2002, they are a Hemi-style which go right into the valve covers, hidden under the individual coil packswhich can be removed by loosening one nut I believe. After you remove the nut, pull straight out and you will see the Spark plug cap is attacked to the bottom of the coil pack, use an extension and a spark plug socket preferably with a rubber grommet inside it or you will play hell getting the plugs out of the wells once they are loose.

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

Change spark plugs

My 2004 Verona had factory installed "NGK BKUR6ETB" regular spark plugs which I replaced at 30,000 miles. The 2005 model year is supposed to have Iridium spark plugs. To replace the spark plugs: 1. Remove plastic top engine cover. 5 nuts 10mm socket. 2. Unplug connector from each ignition coil. qty 6. 3. remove 2 hold down bolts per ignition coil. 10mm socket. 4. remove ignition coil, lifting straight up. 5. Spark plug is now accessible, use deep well 5/8 spark plug socket to remove.
