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?
