good work !
good work getting it running ....here's some background on true/smooth running.....various computerized engine management systems have different measures.....but .....if you go back to the old days when you had coughs and splutters from one or two fouled plugs, a torn intake boot letting loads of unmetered air in or you pulled a high tension plug wire off and got a dead cylinder.....or you rotated the distributor to alter your advance and retard timing you have a rough idea of what they are trying to measure

also .....keep practicing your DIS 57 skills .....first test is to activate the E box fan ! (listen if it runs quiet)......second test is activate the secondary air pump !....third test is get your fuel trims and see how each bank of three cylinders is doing ....this can give you loads of tips about lean codes/poor injectors/etc etc.....4th test is to see your wheel speed sensor output in real time ....5th test is activate the fuel pump and listen for the low hum of the motor/pump....loads of fun learning !......your diagnostic skills will improve greatly....you will save beaucoup dollars and be singin "king of da road"
