On a Tuesday I topped off the gas (I have a habit of filling the tank, when the gas handle pops, I pour a little more gas in to round to an even dollar amount). On Wednesday evening after driving to work and doing some running around town, the check engine light turned on. I had the code diagnosed and it was a P1450 UNABLE TO BLEED UP FUEL TANK VACUUM. Then on Thursday morning when driving to work, the gas lid starting making a LOUD vibrating noise... Thoughts?
