1990 camry fuel out exhaust pipe gauge drops rapidly
 i have a 1990 camry that is running extremely rich. Fuel is coming out the exhaust. Fuel is coming out of the line in the charcoal cannister. Fuel pressure is in the range specified. cold start injector ohms at specs. Timing is in specs.As you drive down the road you can almost watch the gauge fall as your driving. Plugs ar obviously fuel foule with a miss. This is a 2.5 V6 motor.ICS and TPS are in specs. There is no codes in the computer. Any ideas or elp would be great. Thanks

Check your injectors to make sure they are not dripping. Dirty injectors can leak fuel. Replace your HO2 sensor.

Re: 1990 camry fuel out exhaust pipe gauge drops rapidly
Ditto. Some experts advise changing O2 sensors as scheduled maintenance every 80 to 100K miles regardless of a check engine light. Fuel in the evap cannister could be a bad check valve or vent. One sign of leaking injectors is hard starting.

May possibly be your Engine Coolant Temperature sensor. Test it.
