| all the connections (electrical). I would 1 of each so that you can do your own diagnosis 1) extra coil pack
2) extra injector (doesn't matter what size - you will just use this to connect to the wiring harness while in hand to see if it clicks)
3) extra spark plugs
4) extra working MAF
5) extra CAS chances are given the winter - the car is running rich for cold start and fouling the iridium plugs - especially if you are not starting it much. I am chasing a similar problem now. you can check everything with an extra part as I listed above. You can swap coil packs / check the power source to the injectors / and swap out spark plugs (I would save some pfr6b-11 or 11b just for this reason). You might want to disconnect your o2s so that you dont have the ECU pulling and throwing fuel at the Z at idle. ofcourse, do this when the car is warm and make sure your Temp sensor and TPS are in spec. A conzult helps as well to monitor everything and to perform a power balance test.
