97 Explorer XLT Check Engine Light

Hello, I had a check engine light on my truck about 10 days ago. I took
it to the dealer, and they diagnosed the EVAP vent solenoid and EVAP
management valve were bad, and replaced. Then, about a week later I
take it in for another check engine light, this time an error code 420.
They reprogram the computer and send me on my way. Today, two days
later, I have yet another check engine light. I stopped at a local car
parts place and they pull the code...this time a 455, which indicates a
gross leak in teh EVAp system. I guess my questions are as follows:
1. If they pressure/smoke tested the EVAp system, is it possible that
it has developed a gross leak in a week?
2. Could a sensor in the EVAP system be bad, causing this error?
3. Could a faulty EVAP system somehow cause a single 420 error code by
droping to much fuel into the engine?

I am taking it back tomorrow to have them look at this 455 error. I am
just feeling a bit confused.

Thanks for the input.
