ok guys having an new running problem,
this is going to be very hard to explain so please bare with me....

driving along at a normal pace (flat road) i increase acceleration gradually up through the revs to about 3500rpm,
i develop what i would say is almost like a miss fire then a popping noise coming from where the intercooler is and a
metallic noise clanking? from the mid to front end of car.
this will happen through out the revs and gear change for about a mile or two,
then be ok for a day or two.....

front end will be off soon so ill check to see if intercooler is ok
