Hi all,
My Gems engined 4.6 has developed a problem when starting from warm. It fires over ok and starts, but as the revs drop lt splutters to a stop. After a couple of attempts it starts only if I can catch it by blipping the throttle and will run well with no further hesitation.
I've changed the plugs, leads replaced the air filter and cleaned the coil pack to no avail.
Any advice please.
Thanks in advance,
Steve.

Clean the idle control valve.
