XJ starts normally then when starting to move it does some "coughfs"and after that apparently everything is fine, but idle misbehaves, sometimes it gets accelerated others simply completely stalls, last drive whenever I got to complete stop the engine died, it starts back again normally until I advance and get to another stop.
I've already replaced recently MAP sensor, IAC valve, TPS sensor, CPS sensor, 6 moths ago fuel pump, a couple weeks ago spark plugs and cables were replaced along with oil, air and oil filters, also brakes main cylinder.
I suspected fuel pump but pressure seems to be fine, while checking at it I noticed that acceleration is not sustained if I press full throttle which seems wrong to me, I made a small video of it:
Any help would be appreciated.
