over the summer i did cap, rotor, plugs, wires. i have since done a new msd box 6al, and new coil and tfi module.

you could get an adjustable fuel regulator. Their like 60 bucks from summit for a holley regulator. then you can adjust your fuel manually.

ok thats right i forgot i need to get one of those. what would i do just run less pressure i guess?

Yes but be careful. Too lean is too hot and engines don't seem to like that.

No need for the AFPR, run the DIY KOEO/KOER/Cylinder Balance Self-Test, ID what is causing (or if it really has) the rich condition/high emissions..... if you have a cylinder missing problem, correct what's causing it. You should also check the exhaust for any leaks, that could be causing the fumes to get into the car.

i already know it has a small collector leak and no tailpipes, but its just really really strong. ive had ppl say they smell gas, i have to say o yea its me. lol

Understand.....but you need to ask the brain that is working with the signals from the O2 sensors and the rest of the hardware, and making the decisions to change the A/F in the engine. The opinion that counts is the one from the brain in charge, the computer.
