OBDII Code P1590
#12
I sure don't was going to take to a mechanic to see if he could pin point the problem directly. Not positive but would it have an effect on my horse power or the way it idles? Seems to take hills slow and feels as if it wants to slow down quicker than it should? Also got that mass evap problem so stuck on what to tackle first!! Got codes 1590 and 0455 thought one may interfere with other. Maybe wheel sensors on 1590 and the 0455 was just going to do pressure smoke test and see where I go from there?!! Thanks Mike
