I have an 06 GTP with ~25k miles on it. For the last 4k or so, I will get a fuel smell under the hood- sometimes VERY strong- like gives me a headache strong! It seems to have started on our way back from a drive to FL with it. I took it to the dealer once and the service manager just came out and looked at it and saw nothing (I've never seen a leak or anything either). He said it could be the purge solenoid venting, but it smells like raw fuel when it does it, not a light venting. He told me to leave the engine cover off and just check it from time to time. I've yet to see anything, but it is pretty darn strong at times.
Has anyone else encountered this? Maybe it's a common issue or something, but they said there is no TSB on it, so I figured I'd check here. Thanks.
Joe
