Detonation Help!

Don't ever put it back on, there is no need for it, all it will do is make you need a retune, stocker is good for over 300kw and loads of boost

oh really ???

thats good to no thanks again

a stock tune wont ping, get it to a tuner! you have a sensor that has shit itself, something wrong with the fueling eg clogged injector or dead pump or someone has gone and wound the base timing up, plugs wont do anything.

everyday you drive it the more damage you do to your pistons and bearings!

i read around today and there has been a couple of ppl with the same issuse caused by the wrong plugs im not saying your wrong or anything i am willing to try anything but its my daily...

this is something i found

A spark plug does not make your engine run hotter or colder. The terms hot or cold refer to the temperature of the tip of the spark plug itself. The plug must keep a temperature of, between 752 and 1652 degrees Fahrenheit. If it gets too hot it can fire off the air/fuel mixture at the wrong time. This can cause detonation and/or pinging which will put a hole in your piston... not good. If it gets too cold it will not burn off the carbon and fuel deposits on it's tip and the plug will foul out (stop working) not good either.

and this is a link to someone else that had the same issuse caused buy plugs..

If you have a plug from the opposite end of the scale maybe or the tune is right on the edge of detonation but it is unlikely with a stock tune as they are so bloody rich and have all the timing pulled out of them.

Sounds more like the typical misfire than pinging to me from what I read in that thread but I could be wrong.

i have been busy cleaned the afm and intake pipe

changed the plugs

checked the pump Which i think may be on its way out which is one thing that could be the issue leaning out becuse the pump cant supply fuel?? it is starting to sound slugish when its primeing

also there is a bit crap in the filter of the pump so wont be suprised if its f*ked

checked the knock sensors..this was intersting one of the knock sensor loom plugs the one beside cylinder 4 an 5 is broken the plug clips in but is dodgy as and the actuall sender was only fingertight will this cause it to ping ive read that in improperlly torqued knock sensor can cause pinging

finally got time to run diagnostics and got some codes 23 and 45 idle switch and leaking injector think i have found my problem

[Rolls]

we all told you it was almost certainly the fuel pump or injectors...

took out injectors today and there shagged all of the hard plastic casings round the squirters are broken off or cracked they eould be leaking like a siv lol gettin new one tonight will be in tommoro hopefully all systems go

[BOOZTJUNKEY]

all roght my cheapness bit me in the ass i did not reseal the injectors and the pingin is still there and the ecu is shooting the same codes if i am even reading them right the first code thats throne is 23 which is 2 long flashes followed by 3 fast flashes which i read as 23 which is idle switch yeah?.

the next lot of flashes confuses me cause i get 4 fast flashes followed by another 5 flashes which i read as 45 and is injector leak but is supposed to be flashing so fast on the second read out?

and i discoverd my flange gasket is gone on my turbo and is leaking could this contribute in any way

[BOOZTJUNKEY]

ok im getting close to driving the car down to the dump becaus same issues stil..

in the last two weeks i have resealed the injectors which did not help. but i did not use genuine seals which im not keen putting genuine one in on week end

but have also put a walbro pump in to have the same issues now i think it maybe something to do with the tank itself or one of the feed or return lines because i bought a genuine fuel tank inspection flange seal and i still had fuel leaking out of there not as much as last time but still enought to be fumy as in the cabin..

so i bought some aviation form a seal i have used it before to seal tanks with no issuse but on when i put it on this one all around the fange and just around the ends of the feed and return at the tank my pingin has got a whole lot whorse so it may have something to do with it but what ??

Cracked feed or return maybe sucked some form a seal has been sucked up any brainstorming will help thanks
