xj problems
hello all I recently bought a 98' xj8 4.0 as a spares repairs car
it is a running car but has its problems (mice under the inlet for starters)
it starts and idles fine but anything more than say 5% throttle and it will start missing or cutting fuel or something
so far ive checked coils and plugs, they seem to be working fine although plugs are a bit carbony
removed the throttle body and cleaned it all out including the sensors
changed a knock sensor as mice had eaten the wire
it came with a spare fuel pump in the boot so I think the previous owner has changed it
have had it plugged into the scanner but theres no codes after I replaced that knock sensor
any ideas about what to check next? will be getting a video of it tomorrow show the problem

Check the gap on the plugs, usually over gapped plugs create acceleration issues. I would clean the MAF with a MAF only cleaner and check for any vacuum leaks.
