That's what the book says a code 32 is -- '91 L98 auto -- would replacing the EGR and/or O2 sensor fix this?
The SES light comes on after about 20 minutes or so of (only) highway driving... I'm going to be replacing the injectors soon anyway so replacing the EGR at that time should be a minor part of that big job...no? Thanks all! |

If it takes time, then it's the valve.
Also check the vacuum line to the valve. |

Yes, intermittent "miss" when idling in Drive, after warm up (smooth idle when engine is cold)...

back to what I said, check the valve and the vacuum line to it.
the O2 isn't a causation here. as a frame of reference, the EGR does not open when cold. It happens after the engine enters closed loop. With that said, if the code 32 appears when the engine is cold, that means the switch has failed the start up self test. |

the switch has failed the start up self test. That is if the ´91 EGR has a switch, or were you not referring to that. I have a ´91 and mine does not have the switch, the earlier model years had the switch. It´s ECM controlled. This is from my FSM. EGR circuit description, brief, With the ign. "ON" engine stopped, the EGR solenoid is de-energized and by grounding the diagnostic "test" terminal, the solenoid is energized. The ECM will check EGR operation when: *Vehicle speed is above 30 MPH, *Manifold absolute pressure is between 15 kPa and 70 kPa, *TPS is between 8% and 30%, *No more than .4% change in TPS. |

ok... replace "switch" with "solenoid."
I think you will find your 91 has one. My 92 does. Something has to open to allow vacuum to get in. |

Will do. I didn´t know the solenoid replaced the switch. Have I learned something as well  |
