I believe it ODD no one has ever had this problem. It is not a clutch / tranny issue.
My car ran like that for the past 4 months, the past two weeks consistently even when car was cold.
IT WAS THE DAMN MAF SENSOR!
I had it facing towards the radiator, as opposed to firewall. I read it somewhere ( Viprdude's 200sx Thread ) some posts talking about how that could affect the car. And it does, I can vouch for that. I returned it back to it's normal spot ( had it facing the other way for clearance ) and it went away !
so it was the maf facing the other way, silly mistake
