2005 Kia Amanti. I had codes P0401, P0174 and P0171. I did change mass Air flow sensor, Egr vacuum switch, Egr valve, clean the egr tube, put new egr hoses, change Map sensor, change timing belt, water pump and so on.I did spend a lot of money.
I need HELP. ! After I did all that.I did clear the codes. Hard to start /crank. After start. The car drives the same like when I started the problems. Nothing change. When engine runs and I stop the car wants to move/go and the engine runs with rough idle, misfiring, hesitation, lack of power and sometimes stalling.
The code came again but just one, P0401. Can you tell me how to fix it or what do you think is the problem?Any professional suggestion or answer? We did try everything.
Thank you,
Takis

Do you have access to a scan tool? We need to perform an EGR actuation test to see if the EGR is actually getting power to work. Also, it sounds like you have already done a lot. Did you check the intake where the EGR mounts to make sure nothing is plugged?
