That's car I'm having issues with. The car is cutting out like it has a bad spark plugs. Not all the time though. It runs fine until it gets warm. Then it cuts out under any kind of load. The check engine light never comes on. I'm getting frustrated with this darn thing.
problem: Cuts only when warm,acts like there is bad spark plugs.
a: replace all coils $400.00, use msd not factory stuff
b: replace all spark plugs.....got denso iridium plugs, still cuts out
c: mass-air meter has took a dump
d: sell car
e: blow up use gap insurance....no I'd replace engine before then
So please, help me out... do you have an idea?

1st get rid of the irridium and get just reg. copper plugs .... clean the Mass air with a non clorinated brake cleaner.... if its a bad coil it should throw a miss fire code and there is no need to use those MSD,ACCEL ect ect coils they are not need till you are push major amounts of boost and maybe try and replace the fuel filter
