Quick update after being away for a while. Back Investigating Rough idle & Misfire at cold start and warm start issue.
Update ( 11/6/2022 )
Corroded Air temperature sensor terminal on Airflow meter. When temperature comes up to normal, resistance goes out of spec and produces reading -14c hence the MAF flap shuts and dumps fuel and stalls the engine ..Fixed the corroded terminal and all is good now
- Removed and Clean ICV with throttle body cleaner. Yes lots of crap came out.
- Fitted and its a lot better at idle but still have misfire when at operating temperature.
- Struggles under load when engine reaches operating temperature.
- Its is pointing to something ignition as misfire when everything is hot and under load
Will replace next items below. Ordered and waiting to turn up.
- ignition leads/distributor/rotor/spark
Song -Massive Transit
