misfire dealer cannot fix it
I just have someone did a swap of a 2001 gsr into 2000 Lx civic. I use the 2000 si harness and 2001 gsr ecu. Random misfiring in 4 cylinder. Change the ignition wire. spark plug. distrubitor, and fuel regulator. Check the fuel pressure, injectors, map sensors, no problem with them. Then take it to the acura dealer and have valve adjustment. Still did not fix the problem. Don't know what to do. Need some serious help. Thanks

did you do a running compression? if it is isolated to one cylinder, check the plugs, and other parts related to cylinder that has the problem.

Re: misfire dealer cannot fix it (BatuKing)
Since you pretty much replaced your whole ignition system,all that leaves is fuel and or/ mechanical problems...
Id try running some sort of intake system cleaner such as Seafoam or BG through the intake to clean any buildup on the valves...If that doesnt help,swap injectors from the affected cylinder w/ another and see if it follows it...
No other codes right?
