Hi,

My car listed above is a Toyota IST 1.3CC VVTI. (NCP60)..
it has small rattling/ ignition sound at low rpm's. It is not regularly happened but. I notice it sounds when gear shifts with low rpm's. When at highway speed of 100 kmph , it comes. Same stage if overdrive off. No sound noticed.
And also i have notice A/C clutch gives some horrible sound. I have asked mechanic to check and he has tied up the belts. Now less A/C clutch sound comes different speeds.

Is the A/C clutch sound is the reason for ignition sound or all these are two related things.

I have checked VVTI solenoid and engine sludge. All are clear.

Thanks.

Good morning,

Can you upload a video of the noise so I can hear what you hear?

There are so many places noises can come from. That is why it would be best fro me to hear the noise.
