1986 Trans AM LG4 5.0L Carb - ODB1 Code 34 MAP Sensor Circuit Error (Signal Low)
Greetings,
I need to smog my 1986 TA with LG4 305 Carbureted engine and I am getting ODB1 Code 34. Swapped out MAP Sensor, still getting error.
What are the next things to do to troubleshoot?
Let me know,
Thanks,
Ed

did you swap out the vac sensor of the baro sensor. the LG4 doesn't have a MAP.
vac line connected to vac sensor? baro sensor port opened to atmospheric?
