Ok, got some of that. I disconnected it again and runs 10 times better.
Possible places I could check for leaks? I do not have pressure test system. Could I use smoke from a cigar? Any suggestions?
Trying to get my hands around what you said. So with preset values even with leaks how does that happen to still run smoother with MAF disconnected? Should I try cleaning the new MAF I received? Or return it for another new one from where I got it? The error codes I am getting are P0103 and P0175. MAF error and system 2 rich bank 2.
Now my car has 155k miles, should I be concerned about the Diverter valves and N75 valve? Change those at this mileage? are they known to go?
Thanks for the help.
