Hey guys, I changed my spark plugs about two weeks ago and for the past week or so i've been smelling this strong gas smell inside the cabin and from the exhaust. and when I get out of the car and walk around it, it smells like a gas station. This did not happen until after the spark plugs were changed. I'm afraid I could've overtighened them because i put them in a bit tight. Also, I have a check engine light for the cat conveter but i'm going to have it read tomorrow in case I have a misfire code too now. I'm also gonna pull them out one by one to see if they'er covered in gas or oil then put them back on snug and not super tight again. I used NGK pre-gapped lazer platinum plugs for about 10 bucks each.

Any ideas guys?

Thanks.

Oh I also forgot to mention I've been running the car with low fuel. Since I've fixed it. Money probs....

I'm gonna fill her up tomorrow with premium and add some techron booster and see if it helps.

Codes I got back were P0171 and P0174. System is too lean.

Any ideas?
