Flooding Engine When engine gets to 155 degrees
1988 firebird floods out after startup when the engine reaches 155 degrees. 305 V8 throttle body fuel injected. Engine coolant temp sensor has been replaced. Any suggestions?

Yes, look at the O2 sensor signal along with the BLM (long term fuel trim). A misreporting O2 sensor can drive the BLM up to the point of extreme rich.
