Sorry, I left that info out and I have -3- gas caps. Codes are: P0551 - pressure circuit; P0442 - EVAP; P0455 - Purge Valve Short; P0456 - same as P0442. Like I asked; how much should I expect 2 pay for vacuum seal & how long should it take to fix. I do NOT mean to sound ungrateful; I spent over $500 with 2 mechanics that have licensed garages and the lite is still on. How do you think I got -3- gas caps. (smile)
