Audi A3 1.8t 98 Misfire

[Jasonreed5856]

Hi guys I’m new to PistonHeads but I am in need of some help.

I bought my Audi for £400 good condition inside few scuffs on outside 124k on the clock with full service history.

Straight off the bat I needed to have water pump and timing belt done so I did so car runs and drive lively so noises knocks or bangs.

I have fitted a ram air induction kit on the car which as follows I think is what caused my problem, I noticed on the side of the air box is the IGN AMP after doing the work the car sounded great and drove fine as usual one morning I got in the car and after about 2 miles I started to get a misfire, I changed plugs no diffrence I changed the failing cylinder IGN COIL for another till I found the problems ( Cylinder 3)
No matter what I do I get no spark on that cylinder which bring me back to my previous comment the IGN AMP has been loose most probably banging around in engine bay.

Is there a Wayne of fixing or testing this before replacing and could it be anything else thanks guys 🤙🏻
