P0300 random misfire, slight rough idle good , by the way your repair is good you dont want a identified misfire, Lets start by what it is not. Not a misposition sparkplug wire you would of gotten that cylinder code, as misfire, Oh try this got carburator cleaner? spray safely along the intake gasket, How about inspecting the vacuum hoses especailly at the map sensor. Here the thing you got. a vacuun leak. on a 5.7 a vacuum leak causes random misfire, by definition P0300 means 2 cylinders or more. By experience its a vacuum leak
Offhand, it would appear to be an air / fuel problem. Initially, check the air box / filter. Verify that there is no air leak and that all air coming in through the carbs passes the filter. This also happens when the air filter and its enclosure has been replaced with open breathers such as K & N's or the exhaust system has been altered.
Yes, it could (and probably is) be an air leak. Check to be sure the carb is tight in the intake manifold, and make sure the hot-start isn't loose and is sealing properly. Also make sure all of the exhaust system joints are tight, an air leak in the exhaust will make a four-stroke pop and backfire like an old work truck with no muffler...

it will pop on accelerating like a misfire only when i give it the gas faster than normal. It will happen also when i am riding and also with a slight hesitation. If anyone has any suggestions it would be great.....thanksThe first thing I'd try is some Seafoam in the gas.,,
