Im sure this has been asked but can't find any post but I have a 95 suburban k1500 with 5.7 with low load rough running miss. When idling it runs fine but driving down the road with foot barley on gas just to hold the speed it has a miss but when you give it gas it smooths out...only does it driving down the road as I said with low load on the gas. Just did plugs, wire, cap and rotor tune up and it did not fix mt issue.....
