Revs stop at 6.5 K every now and then...
Hey guys,
This one has been bugging me for a while.
Basic car info:
104,000 km
20,000 since rebuild
Every now and then (happening more and more lately), l will loose power at the top end of my rev range. At WOT, the revs struggle between 5K to a final maximum of 6.5K (sometimes only 6K).
I've done some searching on the forums and l'm down to the possibility of it being the coils and/or plugs, OR, the cat.
I'm actually leaning towards the cat, as there isn't that "blender" sound through out the rev range and the car doesn't miss fire or anything. Plus, the car runs like a dream on other days.
There is one strange sound though, when the car is at it's 6.5K max, the thing sounds like a chainsaw (I have the borla cat back fitted btw)! I don't know if it always sounds like that and l'm only noticing when l have the issue though...
Anyway, getting to my point, is there anyway l can narrow this down? How do l know if the cat is dead?
If it heaps, i can video tape the sound/revs.
Cheers.

You have to unbolt it. Look inside with flash light.
Also buy some extra bolts and nuts, they have a tendency to get stripped or be weled on.
