That is strange,
Ive had the clicking sound before but it went away after i pulled the top off a few times.

I took decel and cold start off my engine, i had a clicking sound but it went away and it seems fine now i think my car got used to them not being there anymore somehow.

I have no idea what could cause the surging though,

I could assume its not electrical

That leaves Injection and mechanical i think.

Mechanically it sounds -good (to me) idle is smooth if you take out the surging

So maybe something with injection ...maybe AIR and fuel head area? wur? (whatever Wur means thought id mention it because it seems its always a problem with some cars)

Fuel delivery?
Vacuum leak then vacuum sealing? is that possible?

Hopefully one of the Jedis here can help?
