147 engne issue help needed asap

Hi all I have a 147 2.0l TS, for a while now the exhaust has been blowing, standard back box has corroded badly and its now started rattling further up the system and today the car is not pulling well under acceleration feels like its missing a beat or something (sorry for the very untechnical terms)
also when I lifted the bonnet the engine is moving quite a bit i'm wondering if the exhaust is causing the movement or if a cylindar has gone (i'm hoping not) on tickover the engine runs sweet but once I give it some revs the engine starts shaking a bit in time with the exhaust rattle, theres no black smoke and theres been no obvious noise to start this.
I'm wondering if its the cat which has gone but unsure if this would cause overall symptons.

any help or even ideas would be very much appreciated ?
Thanks guys

Difficult to tell from your description - if one of the cats was breaking up it could cause a partial blockage and create issues....or it could be a faulty coil pack, or, probably much more likely, the ever-popular oil down the plughole joke - normally on number 1 cylinder, where oil spilt when topping up runs down - or of course oil can leak past the seal on the cam cover. If you get a build-up of oil there it can short out the HT lead to the plug, causing a misfire. This would normally trigger a warning light/message, though....
