1999 F150 PO443 Evaporative Emission. Need Help
Good to know, I don't really notice my truck running any different but if the check engine light is on I better fix the problem.
By the way, on the Canister Evaporative Valve it has a tag that says it's got to have 1PSI running in it. Do I have to worry about pressurizing the new one or will it create its own pressure once I install it.
Thanks,
Chris
