O2 sensor help...

[Hozer 88GTConv]

Thanks, Jeff and Joel.
It is running well now, the strut tower connector was a problem and replacing the 02's too seems to have solved the issue.
Unfortunately, I had to crank my regulator up to 49psi at idle (vacuum off) to get the desired readings.
KOER tests show the 02 faults cleared. I did it three times and it drives very well. The Anderson PMS shows the 02 readings flip-flopping back and forth btwn lean and rich. Throttle response is excellent and more importantly, the strong smell of gas at idle is completely gone.
The theory that the car was running lean, so the computer was dumping as much fuel as it could seems correct.
It definitely is running strong, but now I'm wondering if I have another underlying problem in the regulator or injectors.
49psi seems like too much for 24's even with a 76mm MAF/70mm tb, tw heads, etc...
cheers...time for a beer.
I'm taking it the dyno this week for final tuning with a wideband 02.
Might reveal the regulator or injector issue.
