Ok, here's an update fellas. Put in an el cheapo gauge to get at least an idea where I stand. I started first without the mod to see a baseline. I'm getting a slight rich read at WOT, but I'm running really lean on my idle. When I reset my computer and put the altered MAF in, to my suprise, I wasn't lean, I was way rich. My sputtering is apparently coming from the engine trying to flood itself. Go figure. Anyway, I'll update everyone once I get my a/f regulator installed and play with my a/f ratio at various rpm points. The unit I have will let me adjust 11 points in 50 rpm increments from 500-8000rpm. Of course I won't need to go that high seeing as how we redline around 6500 right?

Here's a quick question though. Anyone know if a new wide-band planar type oxygen sensor can be put in place of an older narrow-band one? Or should I just install it separately when I get a wide-band a/f ratio gauge and use it only for that. Also, which Oxy-Sens should I be getting my signal from on a narrow-band gauge? I was going through my shop manual and see a diagram for four sensors A-D. Only two of them, from what I can read from my electrical diagram, feed a signal wire back to the PCM. Any thoughts?
