Exclamation Help needed for newbie!

Hey all,

Im new to the forum.

I have brought an Audi A4 B5 1998 wagon (1.8L)

I brought it with some problems, however there is one I can't work out.
There is a slight shudder/misfire at idle. The mechanic I took the vehicle to has checked the injectors, the coil pack, leads and plugs were changed.

I am yet to check the MAF and underneath the rocker cover for sludge build up.

Today I noticed a bit of a tappet noise as well.

More information regarding the shudder/misfire:
Only present at idle
When accelerating it disappears
There is a slight bit of lag when under heavy acceleration
Stalls on cold start
Small amount of engine movement at idle

The car has 180000kms on it and I have added a valve lifter additive to try and free what I think may be a stuck hydraulic tappet.

The mechanic said there was a slight decrease in pressure in cylinder 3 at start up also.

I am yet to do an oil and filter change because I would like feedback beforehand.

Thanks,

I look forward to the response of the forum
