    You can use either a FlashScan V1 or V2 to scan the 98 K3500, you may be able to tune it if you want as well (that controller is end of life for EFILive support however).

    Fire up the Scan tool and connect to the vehicle, validate the PIDs, then really just look at the basics. ECT, RPM, Speed, Spark, LTFTs, STFTs. If it starts missing hard, you should see the RPMs drop.
