Re: Idle/Vacuum Problem was Fixed and Now Is Back AGAIN!!! 200 85

posted by  someone claiming to be daniel on  Sun Sep 16 06:14 CST 2001 [RELATED]

Heeding your advice, I am starting from square one. The frequency valve just seems to be following commands. And get this, when checking out the frequency valve duty cycle (which was 50%), the oscillation practically ceased after unplugging the O2 sensor (frequency valve giving a steady buzz). The car still hiccups a bit, but no gross oscillation.

Directly testing 02 sensor and adjusting mixture is next on list, but sounds like a new 02sensor could be in order (a sound sensor is needed for proper mixture adjustment anyway). Know where I could get one cheap (naturally)?

Thanks for your advice!
