Hi, My wife has a 99 ford escort sohc, I just replaced the EGR and the DPFE and thel hoses to them and gave it a tune-up but the car still runs bad when you first take off, the engine light is now off, it did have a p0401 code then I replaced these parts. Is there something im missing. Thanks for any help
