Raw gasoline smell in the engine compartment.

This is a continuing saga. If you want the whole story see my thread "Multiple Misfire....."

Yesterday the engine ran almost perfect on the first trip of the day including with the engine fully warmed up. On the 2nd and 3rd trip of the day it was back to misfiring a great deal. I also noticed a raw gas smell in the cabin at idle with AC or vents on, and I detected it under the hood as well. I can't find any gas wetness anywhere.

check your fuel pressure at the fuel rail and check the regulator vacuum line for gas

smells like its running way rich

any codes??

Last code was "multiple misfire". This morning the engine ran pretty good with no gas smell. It was city driving only. I will have it out on the highway this afternoon and report back.

Try new coils? Last time plugs were changed? Multiple possibilities here.

Check the resistance of the ECT sensor when it's cold, then again when it's hot.
