SOURCE: 2005 Chevy Impala exhaust smell
neither one of these would cause gas to leak. sure it is not coolant ? if you think it is gas it is not safe to drive car as it could catch on fire. possible cause would be a leaking injector.

Chrysler has a bulletin out for a simular condititon that involves replacing the pcm. Heres the bulletin number 18-005-04. This is only 1 possible cause , Fuel pressure, coolant temp sensor, thottle position sensor all can cause like problems. Seeing sensor values and fuel adaptives with a scan tool helps pin point problems.

The valve cover gasket change is related only to the extent of needeing to remove something else . There is the fuel pressure regulator and the MAF SENSOR talks to the ECU telling the computer how much fuel is needed for proper mixture of thre air passing into the intake. It is the first sensor in the intake duct coming out of the sir filter. Make sure all the injectors are secure in wiring connection and look around for any other that had to be removed. All plugs mean it isn't just one injector. Unplug and replug the MAF. cHECK THE THROTTLE POSITIO SENSOT. iT RIGHT THERE where the fuel likage is attached.
