[skipppy]

need of help

bout a month ago i changed plugs on my r33 gtst to ngk bcpr6e and gaped em to .8 mm after a small boost increase caused car to splutter.

This seemed to solve the problem, but i have just returned from a 10 day holiday to find its doing it again but worst.

Anyone have any ideas different plug? gap?

might not be just the plug....

If you were gone for ten days, yhe fuel in your tank would be pretty crap by now.....

Take your car for a long drive (not thrashing it too much, as your car will ping heaps!) Burn up all the old fuel, and put some fresh fuel in there... THEN take your car for a good 10 min thrashing......

If you notice it is still pinging pull back a bit.... dont over do it....

The purpose of this is to burn any deposits off your plugs...

Let us know how it goes after that...

car is fine, derr

was driving down to get some octane booster to breifly look over at boost gauge to find it was boosting at around 1.2 bar.

And after poping the bonnet i found the pipe on cheap arse boost controller had a large split, quick fix all is well.

hehehehehe

thats why i always check first, to avoid posting responses like you last one...

At least your cars ok now...

"""bcpr6e""" You need the 5 rating ones the 6's are no good for Oz conditions.

If you are upping the boost try to narrow the gaps a tad more.

Check for boost/vacuum leak.

MRE, why are the 6's no good for OZ conditions? I presume if your car is completely stock, the 5's would be better, but otherwise, with some mild mods, 6's would be more suitable...
