This guide will help you resolve the misfire in any of the cylinders in a Mazda Tribute 2001 4x4 6 cylinder SUV. I fix it when an expert could not do it. I end up paying $800.00 for nothing. Hope this help you.

Start removing all the mark parts in red circles. (upper bolts from the intake manifold,hoses,vacuum hoses,filter tube,etc)

The ignition coil should get around 1.5 volts to work (at least in my truck) this will change constantly due to the cylinder position. Measure between using the two cables from the coil pack connector The cylinder fire like this:  1,4,2,5,3,6.  So if you don't get the voltage and you get half 0.542v this mean the any of the cable running from the coil to the pcm is broken (most common problem is in the pcm due to the position)

  • First measure the voltage from all the coils. If you get around 1.5v in all of them we will start replacing the coil pack. ej misfire cyl #1 - we place coil pack #1 in cylinder # 4 - this is to make sure you have a bad coil pack.

Test for continuity from the bad cylinder (coil pack connector the pcm) all cables have different color so it will be easy to identify. (most of them are in the right corner) In case you don't get continuity this means the cable is broken. ( use a jumper till you  get continuity) test the connector with the jumper cable connected. Assembly the intake manifold and re-test.

echa9750, have you tried replacing the manifold gaskets? if you did plugs and coils, the upper intake manifold gaskets might want to be replaced now. also with the age, the valve cover gaskets probably need replacing too. i did mine and it seemed to make the engine run better. I dont know why but my guide to do upper intake manifold replacement on this website is not complete. Complete guide is here: http://www.beardeddonkey.com/home/commen...

and full guide for valve cover gasket replacement is here: http://www.evernote.com/l/AJ4SbFRBB_dGfa...

Swap the 4 and 6 wires to the coils see what happens

Great stuff, question, when I was removing the intake manifold, apparantly one of the bolts was not “captive” and I heard it fall, I am confident it went down, because I heard it hit various places in it’s trajectory then I heard it hit the garage door grate. I’ve searched considerably and not been able to find the bolt, any idea where I can purchase a replacement?

Happend to me too. I just went to the local junkyard and they charge me a buck plus other parts I needed. Or eBay, make sure the location is US so shipping doesnt become an issue. Hope this help Good luck

Where are you located I need my 01 Mazda tribute fix…I have no idea about cars only to change tires and ck fluids.?

Are you located anywhere to Alabama? My 01 Mazda tribute is misfiring and oil light keeps coming on.

i have a question regarding the steps above.

1) why are you asking to remove the intake manifold to test the coil packs.

2) if I disconnect from PCM how will I get voltage to test the connectivity.

I will try the method up above hope it works! Mechanic still can't find the problem and it cost me just over $2000 and still trying to milk me with my 2002 Mazda Tribute
