I been told by a mechanic if my car makes the pinging noise it must be from the spark plugs gapped wrong... Is anyone familiar with this?? they told me it fuks the engine up....how do i gap it right???

Also my needle jumps up and down on the rev gauge below 1000rpm, it doesn't do it often but occassionally...Is this a big issue???


Need answers....THANKS FOR YOUR HELP!

vague memory that pinking (det) can be caused or intiated by a wrongly gapped plug but i think thats circa 1930 .....i doubt plugs alone would casue that.

as ru says ...go get someone who knows skylines not just cars and engines to have good look asap.

If your plugs are gapped wrong or fouling up they can cause irratic idilying.

As for the plugs being gapped wrong and causing det its very rarely, normally badly gapped plugs cause bad idlying or un smooth running.
Worse case scenarion if the plug gap was to big and you were running loads of boost and it miss fired it could cause some very mild det.

Thanks alot for your advice guys...But im really worried now, so as i haven't dealt with this pinging issue for this long will i have to be worried even after i fix it due to the damage it has already done on the engine?? Will it likely stuff up in the long-run even after i fixed the pinging issue??

By the way I get steady knocking while holding a steady speed on level roads...

Nope, not neccessarily high up in the revs...I get it at low rev's high rev's as long as turbo starts to kick in it gives out the pinging noise...

Where are you based? either one of us could pop round if your local or recommend a decent garage to take the car to.

It could be a number of things?
