Ok folks, I've had my NA-T for a while now, however I had to smog, so I took all the parts off. I just recently got them back and im having A/F problems.
The problem is my A/F runs rich (11.2)when the motor is cold and after warm up or drive for a while it runs lean, 15.2.
I have to keep adjusting the safc. This sucks.
Forgot to mention, it was running fine before I remove the system and reinstall it.

I have vpc, safc, 550cc high impeadence injectors, tt fuel pump.

My question is? what could be wrong?

Thanks in advance.

all this is at idle.., I use to get about 14.8 as soon as the car warms up. now it's like after 30 minutes after running the car.
Well since it don't sound that bad then I guess I'll just not worry about it..

thanks

I had an exhaust leak for a while that created problems kind of like that.
Your exhaust could be tight when cold and the expansion could open up some leaks. Just a thought.
