Yea your iac is OK. An for the af.this is the temp passing they The maf.

The af is airflow passing the maf and ats is intake air temperature sensor on the scanmaster if that is what your asking. I believe my af is around 8-10 at idle closed loop.

Fuel pressure at idle 37 with vacuum line on, 43 vacuum line off.

Fuel pressure should be what ever your chip wants it to be set at.

Af is what the computer thinks is going into the engine based on the MAF reading. Since you'e running a stock one, there's a good chance it's crap. If you have a parts store stock replacement there's a VERY good chance it's crap.

On your injectors, they're over 1/4 century old and needed to be retired yesterday (if not sooner). I would recommend a set of 60's and a matching modern chip (with all the other preventative maintenance your car needs to keep from destroying itself)
