okay im going to try and be as descriptive as i can about what i've already done to try and fix thiss thing. my car is a 1987 pontiac firebird v6 2.8L that my father and i rebuilt about 5 years ago. ive driven about 60 thousand miles on it since with little trouble.

about a month ago the car started getting hard to start in the morning, and it would stall at idle sometimes. so this past week i replaced the IAC valve and then i replaced the MAF sensor today. i adjusted the TPS to the closest i could get it without a volt meter and i also checked the wires leading from the maf sensor and they all look okay. i also checked for any vacuum leaks around the area and i also could find none.

i do regular tune ups on the engine myself and im just out of ideas. does anyone have any idea why it could still be flashing code 34? the light only comes on when i stop at a stop light when the engine is fully warmed.

 

1. Better off going to the V6 forum or you may end up with such replies as "Get rid of that boat anchor and drop a V8 in it".
2. Code 34 is low signal output... Need to make sure you have 12V power at the orange wire at the sensor and that the connector is tight.
3. Make sure there are no breaks or cracks in the rest of the intake ducting.
4. Check for vacuum leaks. Around the WHOLE engine.
