hi guys, car has been going good mostly with a little hesitation sometimes but not so often that you really notice it much,
what I did notice though is my LTFT was sitting around -9, I then read something that I cant seem to find now about the brake servo leaking vacuum from either the servo itself or the pipe or the check valves can cause this, it also said that to test this you pump the brake pedal and watch the STFT to see if it trys to lean the mixture out and when I did this my STFT jumped up to -35 so does this sound like a vacuum leak? I changed the check valve thats next to the inlet manifold to a new aluminium one and it made no difference, I noticed theres another check valve in the pipe close to the MAF too but havent changed that yet.
whats you thoughts guys?
