Rapid ticking noise behind manifold in service mode

[madbilly]

Hiya,
I put the car in service mode to check fault codes and heard a rapid ticking noise coming from behind the intake manifold, disappeared when I removed the paperclip and returned when I reinserted it. Any ideas what it might be? Secondary throttle solenoid?

Also, I moved the throttle and there was a short of crunchy electrical noise, perhaps from the TPS?

Cheers,
Will

Will,

I’m sure it won’t be this simple but ...

Having never heard a sound on the occasion of putting the clip in, my first thought would be a bad connection on the clip.

Try a thicker one and see if waggling it about makes any difference.

Resurrecting this old thread.
I’m trying to resolve some issues with my car. There is a slight hunt at idle and car is stalling when coming to a junction.
Put the car in service mode to pull the codes and I noticed this same ticking noise coming from behind the plenum.
The rhythm seems to match the rev fluctuation.

Did anyone ever get to the bottom of this?
