What is your question?
I put in new spark plugs and coils. I put a new injector on # 4 cylinder, Cleaned the other 5, Put in new air filter. Put new plenum intake gaskets. Cold start with code cleared it runs great. Drive it for a while and shut it off. Restart and put in gear , engine light comes back on. RPM's fluctuate at idle when at operating temperature. Put one can Seafoam. At low RPM , mostly in 6th gear , you can feel the miss in the motor. Any suggestions would really be appreciated.

Smoke test time. Smoke testing the engine will show if there is a vacuum leak. I target that mostly because the plenum gaskets were replaced, but also because you have an erratic idle. What codes are you throwing now? Are you able to monitor any live data?
