Okay I have a 2004 grand am 6c engine and on wed I went to lunch and thought maybe i was just smelling someone else's car.. I was sitting in a drive thru... but then on the way home it was SOOOO bad I could not stand to have the heat on at all! (mind you i froze it was 22degree's out side) then Thursday morning the same.. maybe a little worse. after work on Thurs I took to get oil changed as it was time I asked them to look under the car just to see if they saw anything and Nope they didnt but hey it was just jiffy lube i have noticed I have used ALOT more gas this week than I should have but does not seem to be Pouring out of my car either. today I filled it back up with gas drove maybe one block down the road parked went into publix came out about 5 mins later as I walked up to my car I could smell gas and when I opened the door it about knocked me out! well I was going to lunch with my husband and some friends or ours whom's husband works at a nissan dealership service department but he said no way they could look at it that day and he didnt have time to look at it on is lunch break understandably so but my husband was there and so was his wife I started the car and WOW gas smell again! so guess I will be taking it on Monday but anyone have any suggestions?? I fear what it will cost to fix this! but I am also scared to drive it till Monday could it have a gas leak??
