99 Galant with 2.4 a/t.Starts and runs fine when cold,when it gets to normal temp (after a 2-3 mile ride)starts to stumble as if it is running out of fuel and will stall when trying to accelerate.Will re-start but as soon as you try to accelerate same thing happens it will stumble and stall even when in park if you try to give it gas it will stall out.Tach jumps up and down in RPM'S before it stalls even if holding the gas pedal steady in 1 spot.Any suggestions greatly appreciated.Thanks for your time.
