my car had same problem but now ok already, go change or service ur ignition coil, that might be the problem, atleast thats the problem found in my car, high rev jerk a little and power lost around 5k right? ask a mechanic to check ur ignition coil then kay? =>

just my humble opinion =>

yr car got bullet or not??? bullet can release the noise

your ignition problem bro.....check coil,cam sensor,timing sensor,coil pack,plug cable,spark plug...have u check it?

 

[lynx_210]

only the sensors not yet check the rest all checked

check ur plugs

if too white >> less fuel more fire (api)

if too black >> too much fuel >> makes more carbon

its ok if a bit yellow-ish...

try tuning ur car if plug s ok..

my rusty cents
