My 2004 Ford Escape; when I crank it up it idles high then idles really low & start to miss then you hear a hissing air sound. When I put my foot on the break & put into drive if misses more unless I idle the rpm to 1 the missing stops but the hissing is louder the more gas I give. Also when you drive it up hills it loses power and speed go's down to 5 miles cars have to go around me. But on open flat roads it's ok & the check engine light never comes on. I put new spark plugs in, new idle control value, EGR value, mass air flow sensor & new vacuum lines. Still no help. I even had guy at advance try and check for a code but there wasn't a code he said, so what can I do to fix my SUV?
have the same problem?
