Gq patrol driving me insane - Ping

X2 on the top end cleaner.. ford also do a bottle which I think works better, and is more suited to the larger engines.

You said you have an exhaust fitted right?? Does it have a cat?? If its been removed the lack of back pressure will make it ping.
Is your TPS adjusted correctly?? I'm not sure about the TB42E but do they run a AFM? Is it working correctly ??

Theres 2 more things i can think of but they're a bit far fetched, are you mistaking a rocker assembly rattle for a ping?? Is TDC on the crank TDC on the cam ??

Just 1 more thing, if you really think its a lean ping, disconnect the vacuum from the fuel pressure regulator and plug it so the motor doesn't suck air then go for a drive. You could also crimp the return fuel line while the motor is running ( and fuel reg connected to vacuum ) and see if the idle rises ( that will just eliminate fuel flow and if its sucking air from anywhere)

Interesting. It does have a cat yes. But the condition is less than good. Perhaps ill start with replacing the exhaust. I have to anyway.

Thanks heaps everyone for your help!

Good exhaust shops in the eastern suburbs of melbourne people? The work i have seen lately is far from good enough.

Its not top end rattle as its not there on gas. Top end rattle is far more consistent.

It depends who you know even then its hard to say, but what do you want from extractors all the way to the tip or cat back??

I need from extractor flange to exhaust tip, with a decent cat, resonator and muffler.

I could make it but i really hate exhausts. More of a pain than i can be bothered with

I can get mufflers and cat for a good price you just need to get flanges, pipe and mandrels. You will save a few $$ doing it your self so what you would spend on a mild steel exhaust you can build a stainless one ??

Interesting! It is definitely food for thought. Id like access to a tig to weld stainless nicely.

Im away the next couple of weekends and will probably wait till i get the company car back if i do it myself. Can take my time and make it micky mouse!

I made a system for my toy out of stainless with a mig with mild steel wire

Attachment 26872

Over engineered, tuned length, the collector i spent about 4 or 5 hours welding and grinding so the air hits a point and splits evenly lol 20 hours all up doing it in the name of FUN haha you just need to play with your wire speed and paint the weld so it doesn't rust

Nice milo tins George!!! Hahahaha
