Run through the spark test before replacing the igniter. The igniter is the last thing to replace on the spark test flow chart.
I cleaned up some of the connections on my igniter, so at least do that on yours. Mine were looking not so good. Clean the connections to the coil too.

I fiddled with the TPS some more today and just checked the computer. Code 7, looks like I fiddled with it too much. I'm going to fart with it more after work tomorrow but I feel like I'm getting closer.

Just to put a bow on this thread, after chasing down all my vacuum and exhaust leaks, the biggest problem was a poorly adjusted throttle body and a bad TPS sensor. Followed the instructions on LCE Performances PDF to the letter and after the initial rich idle from my broken IACV, she sounds great for an engine with nearly 300K on the clock. Next I am going to attempt to either clean or replace the IACV.

There’s 5 ways I know of dealing with a bad IACV.
1. Remove it, clean it, test it, if all good, reinstall it.
2. Delete it, deal with overly rich, bad cold starts.
3. Find a good used one.
4. Update throttle body and upper intake manifold to an 1989 or newer. See link above.
5. Use a Nissan part number 22660-01U10, you’ll need to fabricate a bracket.

I did the later style intake swap. Updated design. No fabrication needed. Keeps everything Toyota.

Yup. No coolant runs through. It is a bi metal valve just no coolant. I don’t have first hand experience, but the way I’ve seen it done is to fabricate a bracket and mount it to where the Toyota one was. Run new vacuum/air lines.

Previous post #16 of mine in this same thread has a great link for the swap
