Is this a po442 code?
getting a check engine light?
Check for damaged or disconnected vacuum hoses. If this checks out you'll want to have a smoke test done. This will pinpoint the smallest leak. HTH. -Jim
might be a loose or missing gas cap~
smoke test?, Jim, that's mighty creative...ain't never seen that done~ not with tobacco smoke~!
Lol, harmless smoke is forced into the fuel system and the mechanic will look for the smoke coming out of the EVAP system. HTH. -Jim
where might the smoke be puffin' out? do remember from my poverty days would simply trim the puffy end off and put the same hose back on~...this is a "slimey mike" repair...what got through my poverty in Wisconsin days...cracked plastic manifolds? bad gaskets? deteriorated rubber?...have a little trouble Smoke puffin out~...something that drastic would hiss and become apparent~ glad to "see" you all again, btw!~
