Have I missed anything.... the vehicle only runs rough when warmed up and driven a few miles

I cannot pass smog check

 

Which engine do you have?

First is do you have any CEL codes stored? Next is how do you know the coils are good - Did you inspect the connectors as well? Have you failed a smog test already - if so what was off - HCs or NOxs? (too high HCs = running rich, too high NOxs = running lean). Have you tested out the MAF? Tested or cleaned the idle control valve? Inspected for vacuum lines and intake tubes or sprayed around for air leaks?
