Change your leads. They will miss fire under load when they are stuffed.

I had a thumping sound when I was at high speed . I changed the leads and it still thumped. I checked all 3 coil blocks,and they were no good, so I changed them. No more thumping. If you pull the 2 leads of one of the coil blocks, start the engine and if the spark goes down,it should be ok. If the spark goes up or is all over the place it's probably no good. I only payed $50 for each coil block at my local Autopro. Hope this helps.
cheers !
