sounds like a engine problem really man, wait till jay or martin come on .. they can probley tell you more, but if i was informed correctly, bad idle , smokey start up pretty much means bad engne if all your engines parts seem to be working good like map sensor and stuff. go get a compression check its cheap to do and easy if you remove the schrader valve

uhhhhhh , well um , 2 and 4 is kinda foreign to me so im sure your not talking PSI, i really dont know how to figure out metric to american standard stuff but you need at least 90 PSI on all 3 faces on both rotors at the least, compression test it again now
