normal checks would be check water and oil...make sure the two arnt mixed ,,, pull valve covers to check cleanliness...check sparkplugs...do a compression test..leak down test is better if you have time..stick a code reader in it and check for faults..
a misfire 5.3 should show up on code reader ...but I would do the same checks..
