well, what are the ways that the cylinder can be exposed to GAS...one way, through the fuel injector...unless yours is equipped with a Jetronic system (entirely possible) would check the ECU trouble codes, perhaps will tell us why it's dumpin' gas.~

If you can bring this to a reputable auto parts store, they can hook a diagnostic tool to your connector and tell us what is going on here~

could be something like low-fuel pressure, or stuck fuel-pressure regulator...you diagnostic scan would tell us~

sounds like a throttle position sensor is worn...that's a separate issue from the dumping of gas....your diagnostics...FOR FREE--they will send manny, moe or jack to connect to the diagnostic plug (small rectangular multi-pin connector, might even say "diagnostic" on it's cover)~

sir if you haven't figured out your problem yet I would bet (because I had the exact problem ) it would be a fuel pump diaphragm that is leaking into your crankcase hope this will help if the problem is not been fixed
