I have 2003 v6 4.3 F150 180KMILES. Changed plugs 3000 miles ago.
Started missing at idle only about 2000 miles ago. Just changed plug wires and same problem. The only light I got in the past 3 months was a "lean error code one time. I get about 17 mpg in Dallas driving. Use shell
regular gas and amsoil oil. Drive 250/300 per day. If I
bought the Analyser would it help me fix this kind of problem?
Thanks Bill W
