Definitely have the engine warm...also if you are able to check the timing
before you go...do so.

these are basic steps I do when smog time

- fresh spark plugs
- new air filter
- new fuel filter
- new oil change
- a bottle of SeaFoam Fuel additive on half gas tank
- run the van for 10 to 20 minutes on freeway speed (I run 20 to 30
minutes)
- show up at the smog station  - let it idle while you wait

let the smog tech handle and pray

good luck
