Hi, I have almost finnished putting crown engine into my hiace van. I have had the engine running and been driving around for a day. The engine runs mint once up to temp and will start fine when cold but it wont run properly when cold. The RPM gauge jumps up and down when you are between 1000rpm and 3000rmp and has a difinite missfire.
Its like the ecu dosent know the engine is cold and needs to run a differnt map. but my temp gauge on the van works. Do they share the same feed?
Any help would be great
