you need to replace the fuel pressure regualtor underneath the plenum , ck fuel pressure if it drops suddenly after you shut the engine down suspect fuel regualtor , use to have to replace the whole spider assembly now i think you can just replace the regulator

First confirm it is either gas or eastter. Wayer/condedste collects at the tail oip as a byproduct of the caralyctic converter on cold rngine It normally occurs on firts start of a cokd enginw. the ebgine idles low because it is col, but should reyutn to normsl after warm uo.. If for sure iys gasolinem and the engine runs eiygh, then angihector is bad, good luck. I hope this helped yyou

replace them the seals at the top leak over time. Its throttle body injection and there are only 2 of them and are easy to replace.

SOURCE: 94 saturn 1.9L flooding out
i bet the coolant temp sensor is bad,,,when the sensor cracks coolant leaks into and wrecks it and then the coolant leaks thru the sensor and into the harness,,,and this causes the car to dump too much fuel because the computer is seeing a temp that is not real and therefore the air fuel mixture is off and flooding the car,,,typical issue,replace the coolant temp sensor and then harness,,like $75 for both at saturn,,do not by the aftermarket ones,yes the cost less but they are junk and will not work either,,,also i bet if you put the gas pedal to the floor or pump it when this happens i bet the car starts and smokes when it does,,,,saturn redsigned the sensor for this reason,it was plastic and they made it brass so now it can not crack and leak,the aftermarket ones are still plastic junk

From your description it sounds like your ECU is believing you are at Wide Open Throttle (WOT) when conditions are to the contrary.
MAP sensor is a good place to start, but their failure rate is seldom, Id be more apt to look at the Throttle Position Sensor (TPS), and while you are at it take a look at the throttle stop and AIS motor/sensor too.
When you open and close the throttle from the throttle body is there hesitation, does it open/close all the way, etc? If you answered "yes" to any of those, look at your throttle stop and kick down (if automatic)
I'd Check the injector too while I'm at it. Does it pulse constantly? There may be a ground issue. or a problem with the ECU.
Another place to look: On the smaller engines with TBIs the male connector cable likes to rock in out of the receptacle. make sure it's tight.
Hope this helps
