My car seems to be getting most of problems when idling, it seems to idle up and down slightly, but when you go to the back of the car I noticed that the exhaust is sorter puffing, it can do it rapidly at times, this has been going on for a while. I took it in to a garage not long ago because I just wanted this sorted, they said it was my injector seals so I had to pay to get them replaced (over £100) he said that he was very confident it would cure but it hasn't.
So with my exhaust still doing that I have noticed another thing with the car, there seems to be this a weird tapping sound coming from the engine, hard to explain but it sounds like two bits of metal hitting each other, its seems to be mostly when I am in 3rd and 4th gear, sometimes 2nd. It does it at its loudest at around 1500rpms but when you get to around 2000rpms you can't really hear it.
Another thing is that my back box fell off on the way to work recently because it was corroded, which is now resolved, but when I drove it without the back box I noticed the exhaust was popping/gurgling and sometimes banging pretty loud to depending on how fast I let off the accelerator, I have no idea if that is normal or not without a back box.
