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.

 

plugged exhaust

 

Still plenty of exhaust pressure at the tailpipe when it's stalling out and it will start right back up.I'm leaning more towards something electrical and still trying to figure it out but Thnx for the input mxmikie

 

om your temp sensors check your exhaust with a heat gun
