its too rich.
Without looking at the car, (stock except for muffler I am guessing?) its hard to tell.
With a scan of the aircare sheet(the back one with the graphs of the various gasses over time) I can probably get pretty close.
With new plugs, cat and wires, it should be ok. Tho some "new" cats are shit and have very little good stuff in them. Especially if you paid not much for it.
Also, just so you are aware, you are doing nothing but wasting money putting 94 octane fuel in your car. Your car is a low-mid compression car with no turbo and an engine map designed for 87 octane fuel. So putting high octane fuel in is simply you giving the gas station $5 more every time you fill up for no benefit.
And, in this case, you may actually be creating more pollution with the 94 as Chevron 94 has no ethanol. Ethanol burns cleaner and hotter. 87 octane fuel has some ethanol.
The one thing I can tell you to do is to check your base timing, but to do that you need to know what you are doing and have a timing light. If your base timing is off(advanced) a degree or two it can cause all those pollutants to rize.
your car was one of the stinkiest cars on the FVT, but I am assuming that was before you did the work?
If you are unable to do anymore on your own, bring it by the shop I work at and ask for me. I will get it thru. And I won't cheat it thru either, it will actually be clean, and you will get better mileage, and better throttle response from it.
