Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 6 / ORIGINAL POSTEROriginal post

The paperwork you sent me says MY 02 and up. Is it the same 99?

POST 7Original post

i have a '99 and this happened to me a couple of months ago. i jacked the car up and explored the EVAP canister underneath the passenger front wheel well just below and to the left of the exterior gas fill point. there are two valves that can be disconnected up front and one in the back engine compartment. these are purge valves. in no particular order i blew into each valve. you can hear the pressure release from an opposite valve depending on which one you introduce air to. i then reconnected everything and tank fills to full each time now. maybe i was lucky but it worked for me.
