Hi, I am looking for some guidance, I have a misfire, or an early rev limiter on my 996.
The engine revs really well to about 4500rpm, and then its just like you have hit the rev limiter.
I've already replaced the MAF sensor, spark plugs, coils, and air cleaner. No change.
It starts really well, idles and revs nicely right until you get to the 4500rpm mark.
Anyone got any tips or direction ?

Thanks,
Schooners.
