Can you do a compression test, if so compare it with a good cylinder. If you cleared the code it won't come back until it sees the problem in more than one drive cycle and misfires have to be seen a certain percentage of total rotations. If it's just rough idle it could be a vacuum leak, IAC, MAF or another sensor left unplugged.
It's a skip and rough idle what vacuum lines do I check and the IAC N MAF have been cleaned, what's the compression supposed to be at? And it said #1 cyl so I changed that coil... I'm lost need help or things to start checking thanks in advance..
