advise needed ! with cleaning product, clean inside or not ?? Options

[Culpable04]

I had the check engine light on so when I got the code it was 71 that's a EGR valve problem so I replace the EGR sistem ( hoses, valve ) the car is driving wayy better now but after like one hour driving the check engine light came back on. and it's the same code ( 71 )

what can be wrong with this ?


what should I be looking for ?

Do I need to replace something else ?

any help would be great.

thanks.

update

I got this valvoline and I cleaned the intake manifold, but the instructions on the product says to spray it inside the throttle body, but I'm not sure if that would damaged the engine or not. would it be ok if I open the little intake valve and spray this product in here ? see picture below

Disconnect your negative battery terminal and just leave it be for like half hour. Reconnect and it may reset the ECu to forget the code, since you may have fixed the EGR problem but not the code.
