UK Car Repair Questions? Ask a Mechanic for Answers ASAP
Hello, my name is ***** ***** I am a professional here at Just Answer. I have noticed that your question was not getting a response and thought I would see if you still need help with this.I apologize for the delay and I hope I can still assist you with this here.
As I am sure you know the code P0174 is a lean code (bank 2) and from looking at your fuel trim reading its looks like you are still dealing a vacuum leak. If the MAF and or the fuel pressure was an issue you would normally get the P0171 to go with it. Are you 100% sure the new intake gasket is still not leaking.
That would be a good idea Joe, from your trim reading this sure looks lean to me.
