wasup, i just bought my jeep not a month ago and ive been trying to solve a misfire problem that only last for about a minuite when driving it cold then it goes away. i knew about it before i bought it and figured it would be a pretty easy fix. the dealership guy said it ran fine until the intake manifold was replaced, and it does look pretty new. so what would be the probable causes here. cause i was thinking it might be the manifold gasket.
