I have a 99 Dodge Stratus that has a problem with rough idle. Acts like its misfiring but throws no codes. Problem is worse when the car is in drive or reverse. When driving it still misfires and just don't run at top efficiency. Have changed plugs and wires and has new egr valve, fuel pressure is steady at 53lbs. Has electronic ignition but compared coil pack to new one and it seems fine. Any ideas where to go from here?

Mine had the same problem the previous owner did a valve job & the timming was off a tooth. It took me like 5 tries to get it right. Did you recently replace the timming belt & not get it right ? Maybe the belt jumped a tooth. Has the belt every been changed it may be ready to give out on you.
Mine had a bad motor mount on the passenger side too.
