Hi , i am driving a 94 Accord with h22a under the hood and accords tranny, and here is the problem: running reach , check engine light comes on high Rpm, and black smoke out of the pipe ,i replaced the egr valve and oxygen sensor (thats what engine light throwing) , but the problem wont go away, also when i set the timing to normal the car is very slow and acting like it doesnt get enough fuel , so i had to set it to advanced. Well , if anyone might know the answers, plz help.

 

running rich= blue smoke i always thought could be wrong, i d recommend if u got a local tunin shop go havem adjust ur air/fuel flow
