2001 Ford Expedition
bought this truck about 4 months ago with a check engine light on... i was told it was a vaccumm
leak but the truck ran good.. the obd2 code that comes up is p0171 & P0174 (Too Lean)
last night there was heavy rain.. idk if that could have a role in it.. but today started it up fine and drove it for about 20 min then started noticing it was missing/stumbling.. even at idle but it comes and goes.. could this be the vacumm leak just now getting worse?? or fuel related
i had low fuel as well ....added some and it is still missing
