Hi fellas,
I have a minor problem with my M20B20 engine.
Sometimes it's hard to start, I had this problem before but only once in two weeks...couple of days ago it's became very annoying cause it does that 2-3 times a day.
It starts awesome when engine is cold but once warm it takes age to start....like it's choking
so far I can say car is regulary serviced, sparks and filters replaced, injectors cleaned,replaced all rubber vacuum hoses,idle is pretty smooth compared to other engines this type...
what should I check?

Hot start problem?

update

funny but now car is cranking too long when cold
it just wont start like before from first turn of the key

sparks replaced recently, fuel filter last year, blue temp sensor last summer (it was not genuine one, swag replacement if that means annything)
apart from long cranking it goes like mad, no issues in driving

Distributor cap and rotor arm? What condition are they in?
