can anyone cast some light ive got a k plate v8 disco injection its got new plugs ,leads,dizzy,rotor,hence great spark it starts great from cold first click runs lovely then settles down nicely as it warms up.but once its driven and warms up it seems to be a bit wooly?? ie not as crisp as usual then god forbid if you turn it off or stall youve had it turn it over spins fine but seems to flood itself no throttle applied.im now looking at air flow,or possibly the fuel filter/housing as the culprits anyone who could advise me would be much appreciated
