V8 running on 4
Hi newbie here straight in with a problem !
I have a 98 Ford Econoline E 150 Day Van with a 5.4 V8 Triton Lump, 65000 miles , had it now for 3 years with no probs, but over the last month it has been starting every time but it is not fireing up on all cylinders (feels like 4, smooth ? )i have to keep my foot on the gas to keep it running, then after a few minuites it all fires up & runs fine until the next day when it does it all over again.
Now, for the last 4 days it will start up straight away & stay running on what seems to be only 4 pots (as long as i keep my foot on the gas) but will not fire up on all cylinders, i have tried it at all times of the day but Ziltch !! which has now put me off the road
Anyone have any answers ???
Cheers, Bob.

Cheers Racerguy, smoothest move i've ever had.
Engine has now covered 65 thou, at last service i was told plugs will not need changeing untill 100,000 miles. Just checked my service invoice & the fuel filter was not changed !!
Hi Lx , how do i check fuel pressure on start up ??
Would low pressure only cut half the cylinders ? & then after 2 to 5 mins of keeping it running with the lightest of foot skill all of a sudden fire up & run like a dream all day long ?
Thanks for the fast replys guys.

Ok people thanks alot for all your help went throu every thing i could today & it turned out to be what Joe said the IAC. Its now running like brand new, nice one.
Next week is going to get a full service plugs, fuel & air filter, oil change & filter & any thing else i can think of including a new idle air control oh & i might even give her a go faster wash 'n' polish.
