1990 Ford F-150 Custom 4.9L Hesitation, Cuts out, Misfire
Posted to Ford Driveability on 2/5/1999

This truck bucks so bad in lower gears that it's undrivable. Replaced EVP and vacuum [...] you get it rolling and in a higher gear it's not as [...] gave a complete ignition tune up but didn't help a bit. Any Ideas? Jess
