I've set the TPS to 16 and it runs a lot better. Maybe got one or two semi chokes, but still better than yesterday when it stopped a few times.


I've also noticed it started to backfire again, but only when the engine was cold. When it get hot it stops backfiring (and before changing the tps it would backfire very rarely).


Gonna try the injector cleaner tomorrow, any idea on the lack of backfire?
