Need Help spluttering at high RPM

[BLK R33 GTST]

hi guys

i'm hoping u can help me, just today i when i flattened my car once it hits around 5500 RPM it seemed to splutter for around 1 second and continue up the rev range as normal. What does this and how do i fix it?

mods are

3 inch turbo back exhaust

Pod filter with heat shield

and thats about it!

P.s i also know that my O2 sensor is gone could this be the cause?

thanks guys

Any more boost than stock?

Maybe plugs - maybe coils.

change spark plugs to coppers and gap em to 0.8. worked for me.

If else fails have a look at your coils, they do cause problems for many r33s and there are many solutions.

Hey Glenn, have a search for misfire, hessitation coil packs, this issue has been covered to death.

A good place to start is here: http://www.skylinesaustralia.com/forums/sh...ead.php?t=51046

This is the approach I took to fix the issue and mine have been running strong for months now, and all it cost me was a few dollars...
