2000 Miata Coil Pack - JDM vs USDM connector??
Hello All,
American, currently stationed at NAS Sigonella, Italy. Posted this on several forums...haven't gotten any replies. I have a 2000 Miata, JDM right hand drive model, automatic tranny One day the car started up really rough and engine shaking erratically. I changed all the spark plugs and wires and it returned to normal. The car sat for about 4-5 days and when I started it, it did the same thing again. Maybe missing cylinders...no CEL but the lamp might be out.. This led me to believe it was a bad coil pack. I ordered a coil pack from online for a 2000 Miata. I went to install it I noticed the electrical connectors on my car were not the same type/size for the new coil pack. The connectors on my car & bad coil pack are 3 pin, but not like the usual 3 pin with one dead space/plastic pin (I think from research, the whole old Tach hookup pin that's removed). I believe this is a difference between EUR/JDM and US models...? Would I be able to splice in pigtails to the new coil pack? I am having one heck of a time finding an exact replacement part!https://forum.miata.net/vb/images/smilies/ononono.gif I've scoured the internet and can't even find an exact replacement Thanks in advance for any help! |
I think it's more an auto vs manual difference but not sure

Splice those connectors!

Check the earth under throttle body.
I had irregular misfires etc for last few months. Found it was very loose other day when I pulled the engine for rebuild. |

Losing power over bumpy pavement sounds like a loose battery ground to me. I had the same issue in my NB1. The stock connectors over time becomes useless and snap. Also check for corrosion on either terminal (+/-).

The battery neg cable connects to the PPF underneath the trunk near the diff (on the 99 at least). If that connection gets flaky, it can do strange things. Mine rusted through and caused my alternator to intermittently not charge the battery. Check that too while you're looking for faulty grounds.
