I need some helpI have a 04 stock SRT with about 43k miles, I'm having problems with the check engine light coming on with code P0456small evap leak.Thisjune the code has offically been coming on forone yearit first came on at about 31k miles, thank god i got the extended warranty man is it paying off, anyways I'v take my car into two different dealerships over at least 25 times in the last 11months. and the check engine light keeps coming on, it usally stays off just about a week every time they rest it and during the winter it usally stayed off a little longer.
This is what they havedone on my car so far in order; spark plugs, Decarb, spark plug wires, one injector, Decarb, injector flush, replaced all hoses from intake system, air filter, crank sensor, O2 sensor, gas cap, O2 sensor, spark plugs, another O2 sensor, and finally catalytic converter. Also there has been many times that they just did road tests and smoke test and gave the usual answer "we found no leaks and reset the light". I need help i'm tired to taking my car in but i still have 25k left on the warranty. Any ideas of what i should do?? anything that the dealership might have missed?? I feel that since the car is on warranty their not really trying everything they can to fix it.

 

tell them to do a flow test, not a smoke test, and check the nvld switch
