2005 Dodge Stratus Q&A
2005 Dodge Stratus Question: What would cause pressure or a vacuum to form in the gas tank?
Noticed the car idling rough one evening - shut it off, tried to turn it back on, but would turn over and not start. All fluids fine, took off the gas cap and out came a big woosh! We're not sure if the air is moving in or out, though. Ran it through a diagnostic computer, gave code P0171, bank one, system too lean. (Not terribly helpful.) Tried putting more gas in it, ran fine until we hit the 1/4 tank mark,then the same thing happened. Erased old code, no check engine light yet, so no new code, but it is starting to run a bit rougher at the half tank mark, so it's not just a problem with the gas gauge itself. Anyone have any experience like this with a Dodge Stratus? We'd like to run some more tests on it, but with no problem until we reach a certain point on the gas gauge, it makes it difficult. - ejeans7
A plugged or defective canister vent valve or a plugged or fuel saturated carbon canister are 2 common causes of this. - dandd
