When Im slowing down and I finally stop..my vac pressure will jump from -15 to -10....and then bobble a little bit between till the idle calms...its weird...It never did it before.
It started after last night....when my cars vac pressure would stay at -10 even when I was slowing and stoped...I figured out it was a leak in the pressure hose connected to my EVAP...so i replaced it but now it bobbles for a little bit....I dont know where the extra pressure is coming from...any ideas ??
