anyone with stage 1.4 have this?

[DarknessofDeath]

after i have installed the ecutune v1.4 i've noticed that the car has this happening when i start the car. the car starts and the rpms goes up and down....giving it a little gas helps out the problem..

i've changed the battery - new battery..interstate..and had the altenator rebuilt just recently. there is a new fuel pump and the fuel filter has been changed as well.

it's recently over the last week or two i have the car stall out on me on a cold start....as if there isn't enough gas going into the engine on start up....
starting it again and giving a little gas does the trick.
but......to give a better idea....if the car was manual transmission....then i would say that there isn't enough gas going into the engine....

i kind of dont think that it's an electrical problem...which is usually what a tech would attack first (pick on the cheaper route-...well that's what they teach in school apparently)...but then again...that includes sensors too...

my guesses would be:
1) fuel pressure regulator
2) spark plugs???? (doubtful on that guess)
3) 02 sensor ?????
6) /////////// i have no clue actually.....??????

that's why =
