Cold start vs warm start, is there a difference? I've noticed this on my OHC.
If i do a cold start and drive normally, the engine feels a bit detuned even after it has warmed up. It's only when i do a few high rpm runs does the engine get charged up.
But instead of ripping the car through the revvs, if i just come to a halt, shut off the engine and start it again (with a warm engine), it suddenly feels lively.
So is the ECU taking in different readings in these 2 cases? Does a warm start give the engine an aggressive map/setting?
I find it surprising how the engine goes from dull to ultra responsive with just a warm restart.
