I have an 03 taurus 3.0 OHV flex fuel that has a miss, hesitate, buck and sometimes stalls at 2000 rpm when pulling out when cold. Once it misses it runs fine after that, and on days its warm out above well say 55 degrees it doesnt miss at all. No engine lights come either. I have done all of the routine maintenance on it, and replaced a lot of extras with no luck. Replace plugs, wires, coil, Maf, Iac, fuel pump, fuel filter, air filter, pcv valve, cam sensor, upper intake gaskets, with NO LUCK. Any ideas? I am starting to think it maybe a computer issue! Appreciate any and all ideas!
