Any reason why my xf s would have a miss in it at 2200 rpm. I have changed the coil, leads,plugs,rotor. I have tried injector cleaning. It is only at this rev range that the miss starts happening and it struggles to accelarate. I have also checked for air leaks. I have taken the car to ultra tune as they had rollers and could run the car under load and they couldnt find the problem.What am i missing.?

Did you convert it to efi or was is it stock. My guess is there could be something wrong in the ecu changing modes from idle to running mode theres are two switches running in series on the manuals one on gearbox and one on clutch that tells the ecu when the car is in motion when both switches are on (clutch out and in gear). Same thing with the auto only just one switch that opens in neutral or park. When I converted mine to efi it was doing a similar thing until I tricked the ecu. Other it could be the TFI Module.

Hope this helps

Nah it has allways been a manual.
