Still getting P0174 code :(
After reading up on this code I thought it was the intake boot for sure but I just replaced tonight and it looked like new with 90K on the car. I also changed the plugs (NGK) and the acceleration/idle improved
So, without throwing parts at it I would like to see what everyone thinks? 02 sensor (wouldnt this affect both banks and also throw a P0171)? MAF (I cleaned it with MAF cleaner)? Air leaks (How do I check for this)? Crank case valve? TB/ intake gasket?
I am tempted to just bring it to the $tealer for diagnosing
