My Jap Spec SPi mini has an erratic idle at startup (cold engine). This symptom however, disappears once the engine is warm. Any attempts at driving the car before the engine is warm results in it cutting out, and having to be restarted. There's definitely a misfire. Scans with my SP hasn't returned any error codes. I have replaced plugs, leads and coil. There's a K&N filter installed and the injector seems to be spraying fine.
The coolant temperature sensor was replaced last year.
The following are vids I made at startup
Any suggestions will be appreciated.
