ok, did you maybe knock the connector off the CHTS? it's on the head on the passanger side just forward of where the heater hoses go through the firewall, if you unplugged it or even knocked it loose it causes all kinds of fuel to dump in

only when warm, it's pretty easy to check just takes ten seconds to pull the 2 pin connector off and push it back on securely, remember the cold engine needs the extra fuel, once warmed up it cuts back on fuel, if the CHTS is bad or disconnected it thinks the egnine is cold all the time and it will keep dumping fuel

--careful, that's where the most evil, brittle coolant hose of all lives... And replacing it it only worse than having it leak...
