Ford f250 4.6 missing at running speed
Our 1998 Ford f250 4.6 idles fine, but when on the highway at running speed it misses really bad. we just had new heads put on it and a new plugs and wires. we are at wits end. Not sure where to look next. Changed the fuel filter. Also there is a vacuum hose coming off the transmission that we can't seem to locate where it goes.... someone please help.
