I didnt want to clutter up the "surging idle checklist" thread with stuff that wasnt related.
You can see my tortured path here.
My 88 runs crappy closed loop
and here
Code 44 without a code 94
I had a bunch off different stuff going on, including a Bad o2 sensor harness, a vacumn line leaking, as well as that oring missing.
I assumed just one thing was wrong, it turned out to be a combonation of things.
My Car is still not 100%.
The car has never run right since I got her back in 1995.
I just learned to live with some things over the years. Not anymore
The quest for perfection continues.
I will continue to update the threads I started with any solutions I find.
Thankyou Stangnet for all the usefull info.
