Hi to everyone

I am desperatley trying to fix my wifes beloved 92 polo 1.3 spfi cat. without much success. It has misfire symptoms intermittently it feels electrical rather than fuel and will last for 2 seconds or 2-3 minutes. I have changed the plugs,leads,cap and rotor arm to no avail. I noticed the engine cut out when putting the air filter housing back on. I thought i must have caught something and the engine restarted straight away. If i move the air filter housing while the engine is running the idle spped jumps all over the place. I am thinking possible air leak which could be the cause of the misfire also. Hs anyone experienced this problem before?????
