    Hey guys have you's knoticed that sometimes when u start the car in a rush and instantly put it into gear that it sputters a bit and sounds like its dieing, just a little bit, nothing to extreme, but is there a way to fix that...?

    and yes i know "dont do it" but im just curious as to y it happens in an auto and what causes it lol

    Happens to me now and again in any gear. Putting it back into nuteral for a few seconds seems to keep the car happy. I've had her die on me once when I was changing from reverse to drive just after a cold start on a hill. But that was all pretty random.

    I hear you on the splutter though. Probably because putting the car in Drive lowers the idle revs prematurely. I know the car likes to idle higher in Nuteral when it's cold. But that's just me guessing :)

    It takes a few seconds for the IACV to find a 'happy place', so if you grab a gear in that time, it will kick and splutter a bit, as far as I know there's no way to get around it other than waiting a few seconds.

    Try it tomorrow...if you listen to it you'll hear it. The engine starts, the revs head up to about 1200-1400 and then slowly come back down again...once they drop below about 1000rpm you're all good. Still without a tacho just wait until you hear the revs come back down a bit and you should be good.

    When i 1st start mine on a cold morning it idles at about 1100-1200 then after a couple mins it drops to about 800. well acording to the tacho anyway. Mine doesnt splater or anything if i quickly put it into gear, but mines a manual.

    if you drop mine into reverse it stalls, or maybe its the missus turning the sterio up, the heater on and having the headlights on at the same time... lol

    Manuals don't suffer from it as much, because when you grab a gear in the auto some load gets put on the engine. When you grab a gear in the manual, there's no added load on the engine, because the clutch is disengaging the gearbox from the engine.

    But you can still notice the difference in throttle response if you try taking off too soon after starting a manual. It's just not as much of a difference as the auto.

    lol i think mine is actually fuel. i was parked on a hill today with the fuel just on red and it spttered, then started it 3 hours later on the same place with just under half and no worries lol

    im starting to think this is an unpreventable problem lol

    If it is fuel then it is preventable LOL.

    Don't run the tank that low...it's not good for the car.
