For the last year or so.........I have been throwing codes for Lean Banks 1 & 2 and Evap Solenoid malfunction, and tried something last night as a possible fix . What I did was take off the rubber vacuum line from the steel tube that runs along the passenger side frame rail to the area under right head light. Sprayed a bunch of PB Blaster into steel vacuum line, Reconnected rubber hose, started engine and idled it for about 10 minutes. Turned off engine and let it it overnight. Today I drove car HARD for about 100 miles and never threw a code all day long!!! Used to get a code about every 20 miles after resetting computer. Anybody else ever tried this? And if so did it last? Thanks Missouri is still alive and kicking!
