I will check and update theread as soon as i finish this,
New LDP valve i check with chrysler here in Toronto, is $163 plus taxes.
Charcoal canister $122.00 Plus taxes.,
i replace gas cap with my friend's 2005 dodge caravan, but light pop again back after one day..,
so my next idea is may be LDP or charcoal canister or may be as u describe here...Hoses..or air filter box hose that usually brakes..i will check..never heard about that one.
Fuel Gas Cap $30.32..
I decide to check first by myself..and then see what happens...
