Hi, i have a 2004 a/t, I recently put in a 34,000 mile junkyard engine. The car runs great, im trying to get it ready for sale but i have a cylinder 1 missfire code that keeps comming on after a while of driving. The code will get thrown usualy after accelerating up to speed and letting off the gas. ex. like while in 3rd gear highway speed for 4th gear upshift.

I replaced the leading plugs with new and replaced all coils and wires with used that i had laying around. same code and conditions.

im making $ off this investment car so im really watching the $ spent. Any advise here is appreciated because i dont know much about our rotarys.
