Stumbling pony(not drunk)

I changed them in september I think, put in some cheapo autolites to get me by. But my intake is leaking(cheapo plastic, but I am looking for a PI one) Its cracked behind the alternator and cracked in the thermostat housing. So im gonna check my plugs because Ive went through this problem before, but I thought the JB weld quick fix was holding up fine. Lol i know a real shoddy fix, but I didnt have money for a 200 dollar intake at the time.
