Most likely your Cat is gone.
Most likely your Cat is gone.
On the cell so I can't get the pix to load...
Pulled all the plugs. #1 normal ashy-ness. #2 and #3 pitch black, crusted electrodes, #4 blackened slightly with normal ash.
Cranked the car with the plugs grounded. No spark on #2 & #3.

2&3 are off the pack on the drivers side, IIRC. I had bought coils on Amazon brand new for ~$90, beck arnley. They were aready mounted in the carrier, just like oem, but no rubber grommet for the third bolt on the bottom.
OK, so I installed the new coil pack, wires, and plugs.Still had the same problem. Rented a compression tester and read 180.180.180.185.
Hooked up my timing gun to each wire and 2&3 are not sending any signal.
So either the brand new coil pack is bad, or my issue lies elsewhere. I reset the CEL, and it didn't come back on, but the car didn't run for long.
Another thing of note: The exhaust seems to be blowing out extra forcefully. Probably due to the whole running on 2 cyl thing?
Tomorrow's plan:
*Check the old Coil Pack with a multimeter, to see if it's bad. Also, check the new one.
*Switch the wires from 1,4 to 2,3.
*Check Cam sensor
*Check the wiring harness connector for broken/loose wires. Apparently, thats a thing.
*Pull the kitty if the code comes back. I know this would not cause the no-fire problem, but better to know.

Think I've narrowed it down a little more. Cranked the car, and pushed hard on the connector, cylinder 2&3 started working. Took it for a 2 mile test drive, cel stated off until the last 1/8 mile. Light began flashing, then turned solid.
Checked codes p0300 random misfire & p0171 system to lean.
No decrease in performance that last mile. This is getting tedious
Even though the connector is tight, try wiggling the wires themselves to see if the motor runs right or stumbles. My buddy went through two coils until we identified a loose wire inside the connector. Both coil packs were fine.

OK. I took the 2 coil packs apart, and made 1 out of the known good packs. Clean the connectors with cleaner Hooked everything up and no codes for the last 3 miles
Glad to hear you found a solution.Originally Posted by Demon I Am

In not holding my breath
Still going? Is it running smooth with no codes or no codes but still a bit of problems?

I've put about 20 miles with no issues
sounds to me like you have the issue squared away, good job

Chasing ghosts is one of the most difficult things to do when repairing a problem. GREAT JOB hope you have no further issues.

Question, does anyone know where I can get the connector going into the coil pack on the drivers side of the car? Mine is missing the latch points, and I think it may be causing the issues that I am having in my car.
I've read online that you can get them through a dealership, and I've found them online. Google search "Miata coil pack pigtail"
