My 06’ GT begins sputtering getting out of first and at low RPMs, seems to be once car warms up because when car first gets started theres no issue. Slow acceleration out of first and second when coming out of low RPM but once out of low RPM the car moves quickly. Car sounds like it wants to die out once I get to stops if I’m not constantly giving it gas. Any advice where to look ? New sensors ? Fuel issue? TIA
