My 1980 242 misses or stumbles under acceleration only.
Also sometimes at idle the idle speed will drop down very low and run ruff.

This miss under acceleration seem to be slightly worse once up to operating temperature.

Things I have tried:
* Replaced both fuel pumps (Bosch)
* Replaced fuel filter
(main fuel pump fuse runs much hotter than any other fuses)
(I can hear the main fuel pump cycling off and on rather loudly from inside car)

* Tune up with cap, plugs, rotor, wires and air filter.
* Replaced fuel injectors and leaking FI seals
* Replaced coil
* Cleaned throttle body carbon
* Cleaned FP fuse contacts
* Replaced oxygen sensor
* Replaced engine wiring harness
* Checked for and repaired any vacuum leaks

I was reading about the IAC valve.
Does a 1980 Lambda motor have an IAC valve?

Any suggestions?

Thanks!
