OK, so the 94 I bought didn't pass smog (I know it technically should not have been sold in the state of CA). The cat was fried and I found some other problems along the way.
Here is the list of things I have done in preparation for getting it smogged this week:
Replaced Catalytic Converter
Replaced Muffler and Tailpipe
Replaced Cracked Exhaust Header with APN one
Replaced TPS
Replaced O2 sensor
Repaired Oil Filter Housing Leak
Changed Oil and Filter
Replaced Air Filter
Replaced Fuel Filter
Replaced Spark Plugs
Replaced Plug Wires
Replaced Rotor and Distributor Cap
Changed to 30 Speedo Gear from 34 Tooth to compensate for 33" tires on stock gearing
Replaced Motor Mounts
I am planning on running a can of BG44k through the tank once I get everything back together (hopefully tomorrow if I can fix the power steering pump reservoir).
It was failing NOx at 15mph: 517 Max, 136 Avg, 704 Measured and barely passed at 25mph: 770 Max, 124 Avg, 625 Measured.
Is there anything else I should look at before I go back to get it smogged, other than rebuiling the top end? The motor runs fine and has plenty of power, the oil wasn't too bad when I changed it. There is quite a bit of build up in the intake. I cleaned out quite a bit from the throttle body, injector seats and what I could of the intake manifold. From my understaning the BG44k should go a good ways towards blowing out the rest of it. I know there is a lot of people behind Sea Foam, but I'm a little apprehensive of pouring things into the vaccum lines or throttle body. I figured the BG44k was a little safer since it runs through the tank. Plus it seems it would also clean out the injectors somewhat.
