Seeing if anyone else has/had this issue?
Have a 2010 6cyl Explorer with 123,000 miles. On cold starts, all good., but after short trips, severe stumbling when trying to start.
Usually takes 4-5 attempts (chug,chug,chug, stall). Seems like can't figure out the mixture. After it starts, runs fine. If left to sit for several hours/overnight, starts right up again fine.
Been going on for over a year, seems to be getting worse. The CEL light is on and the OBD codes are P1633 (KAM) and P0446 (EVAP issue). Looking at the fuse diagram, found the same fuse is used for PCM KAM and the canister vent. Could this just be coincidental, or should I look at fuse/wiring in this area before going down the EVAP system rabbit hole? Is there a known corrosion issue at the fuseblock?
Thanks in advance
