not really shure on this one, started happening for no appearent reason, doesent really seems to be triggerd by temperature, but when I start the car is will start but then die almost immediatley, sometimes several times in a row, if I start the car then give it some gas it will not die, but seems to be acting like a carburetor, any ideas, I bought a can of gas treatment that im going to add next time I fill up, and the spark plugs are fairly new.

 

Did you recently upgrade your intake? might want to check if all pipes are connected thorougly.
