Trouble starting on Mornings ( SR20 )

[Premera]

Fellas and ladies, i have a P11 wagon with an SR20. I noticed a couple weeks aback on mornings when u tumble the car bucks and cuts off no matter how much i tumble and release, the car wont start. I keep my hand on the keys and keep the starter tumbling and after about 3-5 seconds the car picks up and starts to idle low at first then picks up to about 1000rpm.

This was happening before i changed oils and serviced injectors etc etc and continues to happen 2 weeks after a did a complete service. Only on mornings it happens.

Also, what causes a fluctuation in the idling ( hearing it in the exhaust )

Thanks in advance.

Clean your air flow sensor

Are your spark plugs good?

Did water happen to get into your intake while cleaning? (even a small amount like from washing an air filter and not drying it properly)

Clean your air flow sensor - could be the reason

Are your spark plugs good? - brand new Iridium

- i doubt but if this happens, what do i do ?

check the distributor, make sure its seals properly.
if there is any way for moisture to condense in there, you can have these symptoms.

Take out all the spark plugs,spray a bit of WD40 in each port in the engine,wipe the plastic part that goes over the spark plug with a cloth and put everything back together
