Step 2

Remove the connector from the PCM

Remove the connector from the PCM

Step 3

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.

Step 4

              Test for continuity

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 until you get continuity). Test the connector with the jumper cable connected. Assembly the intake manifold and re-test.

Hello I have a 2001 mazda tribute es v6 and cannot get it to run the right way, it was fine tell I decided to wash the engine and the girlfriend took it for a drive short after, I have replaced the coils, sparkplugs, some of the sensors and clean everything related, can anyone help I’m ready to throw the towel thank you

Nathan Stanley - Aug 20, 2016

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
