Re: Drop in RPM GQ petrol
Wondering if it could not perhaps be the Ignitor system that is starting to show its age, been in my lorrie for probably 10years now

Re: Drop in RPM GQ petrol
I very much doubt that Jules. I believe the Ignitor will either work or not work.
Maar as jy hom regtig wil vervang, praat asseblief eers met my?

Re: Drop in RPM GQ petrol
Jules,
If possible , get out and look at the exhaust fumes when it misbehaves. Blackish smoke will tell you that it is getting too much fuel at idle. Float level eratic.
Another possibility is a small amount of water in the fuel. It will sit in the bottom of the float chamber and form a small droplet in front of the main jet.
When driving it will just get sucked through but at idle it will mess with the mixture.

Re: Drop in RPM GQ petrol
Glad to hear you got the culprit in terms of the carb issues.
As for the chi chi chi sound, perhaps try locking the hubs to make sure it is not an issue with them ? Not sure if your hubs are manual or auto locking, but that is generally indicative of a hub requiring maintenance on the auto locking assemblies.
Alternatively, perhaps brake pads ?

Re: Drop in RPM GQ petrol
The chi chi chi is possibly the old school high tech early warning system on the brake pads indicating that they are almost ready to be changed

Re: Drop in RPM GQ petrol
Jack one wheel up at a time and feel the wheel bearing play, you will probably find it is a bit loose and needs tightening

Re: Drop in RPM GQ petrol
Some report back, the chi chi was not the brake pad early warning system, my left wheel bearings was so loose it was scary , the culprit was the lock washer and fortunately the bearings still fine. However I am going to convert as per TourdeFrans my front bearing system from GQ to GU

Re: Drop in RPM GQ petrol
Wow..... that must have been really loose. Pleased you caught it before it got worse, and damaged other things.
