Fuel in pipes

does this car run ? better have it fixed , may be an injector is stuck open , any mis fire codes ? ., exhaust get hot , gas go BOOM ! !

It runs good until u let it idle..the exhaust pipes fill up with gas..so what can he do to fix it?

so there are no trouble codes ? are you sure it's gas ? you could test or replace the IAC valve clean the port while you're at it

Are you sure its gasoline? Usually whenever you see liquid dripping out of the exhaust, it is completely normal as well as a good thing. This means the catalytic converter is functioning properly by changing the molecules from the exhaust to water and carbon dioxide. The liquid dripping out of the exhaust usually is water and is nothing more than condensation from the heat and catalytic converter doing its job. If there was gasoline dripping out of the exhaust, I'm 99% sure it would have set a DTC (Diagnostic Trouble Code) and make the CIL (Check Engine Light) illuminate for a code probably stating "catalytic converter performance" or something along those lines.

I had gas in my pipe once, and suddenly it escaped into the air. Very embarrassing as there were several people present. I sure did feel better though.
