STGold72, the smell of gas may be due to a hairline crack in the EHA valve atop the intake manifold. To confirm that the EHA valve is leaking remove the air cleaner assembly when the engine is cold, start the engine and inspect the EHA valve for wetness caused by leaking gasoline. Typically when the engine is hot any leaking gas will evaporate so you will not be able to observe the EHA valve leaking/weeping. If the EHA valve is leaking you may get lucky and replacing the two green O-rings may resolve the problem; however, more than likely you will need to replace the EHA valve.
