So shortly after I got the car I got a downstream o2 error. Bought a oem and changed a bad fuse and o2 and no more code in over 2k miles. But about 1000 miles ago I got a p0455 randomly here and there every 200 or so miles. Changed the cap to a stant and it turned on even earlier (about 35 miles) so put the original back and same thing about every 150-200 miles. Bought a oem last week from rockauto and its still kicking on every 200 or so miles. Checked vacuum hoses, etc. under the hood that I can see and nothing "fell" off. I don't smell fuel soooooo I dunno. Also when this started my mileage went from 30/31 to 25 and now that its cooler outside 23.8! =( [thumbd]
