1993 Pontiac Grand Prix Q&A
1993 Pontiac Grand Prix Question: Why is my car flooding it's self to death?
Check engine light on? TEST or MONITOR coolant temp. sensor, if it's reading -40F , then it's failed and your cars computer thinks it's really cold outside and is enriching the air/fuel mixture mistakenly. TEST AND VERIFY FIRST , buy parts later......and be sure your testing the correct component....Also , from what I just checked , they sell the sensor along with the wiring 'pigtail' in some cases , leading me to believe you might want to check the wiring also. - ziptie12
