car making a tick tick noise under high power>???

[Kiwiflyboy]

after some idling problems and car making a tick tick noise under heavy load and high rpm(been told could be Detonation) I decided to run some upper engine cleaner through it, nothing really came out exhaust so thought was a waste but then took for a drive.

Idle was smoother and the power delivery was smoother much much smoother had a better kick low down and a very hard to notice VOD compared to what it used to be. like a whole new engine now.

I did still get the tick tick under full power high rpm but not high rpm low power so really does seem like detonation and have reset ECU and finally thrown away my s***ty Shell card (as no 98 octane) and going to run some 98 BP through it to see what its like.

anyone else got any other ideas for the tick tick sound?? i thought maybe a dyno tune on the 98 octane aswell????

ok so 98 octane working well and no more tick tick or ting ting noise under heavey acceleration so thats sweet car still has a slugish or surging between 2000-3000rpm when holding an rpm though.

Well, just put a tin in! (garage told me where to put it)....Done exactly what it said on the tin!!

Left it for 10 mins or so then started her up again.....

Took it for a run.....and nothing! No black smoke? This might be a good thing, engine may have not had any carbon build up?

Anyway, I'll keep an ear out for the noise. Might have just been enough to clear it!
