Will check the bulb,yes the problem was there since we had the truck,but it would never stall out,it would turn over and start immediatly,then about 30 sec. later it would hesitate shudder alittle then return to a normal idle.
The plugs are champion as recommended in manual,the wires were replaced by previous owner just before we bought it.

 

I am betting the plug wires are either crap or on wrong, cheap plug wires WILL NOT LAST and WILL cause rough run problems, even when brand new.
These engines are all aluminum and dissipate TONS of heat and will ruin cheap plug wires in 30 min.
STI, Kingsbourne or Magnecore plug wires are what you need to install.
And make damn sure you get them on the correct cylinder.
