I have a 2002 F-150, 2WD, Automatic, V8 (5.4). Idles and runs rough, same as in other posting, my Service Engine Light is on. Used gas treatment thinking bad gas (water), will replace fuel filter ASAP. How do you pinpoint vacuum leaks? Any help would be great. Thanks in advance.
have the same problem?
