Hi Guys,
Wondering if you could help me... I dropped a friend into town late last night. As i left the city centre, the car began to shudder vigorously in lower rpm's, but as the rpm's got higher, the shudder remained there but was less.
The shudder stopped when pressing the clutch in, something to do with a gearbox possibly? Also, the idle is pretty rough, as if it's coughing and spluttering. There's also a bit of a shake when it's idling in neutral.
I popped the bonnet when i got home and the engine sounded pretty rattley on idle. When revving, (this is the best way i can describe it) it literally sounds like it has a cold!
What can i do? Thanks for taking the time to read!
(Keep in mind, this is my first car. I don't know the first thing about anything to do with motoring!  )
Thanks!
Neil

Pull your spark plugs out see of 1 or 2 are dirtier than others, I had something similar happen to mine, turned out to be the coil pack.

How do you check the spark plugs then mate? It looks like even if you take the coil pack out, it's still a ballache to get to the plugs?

Remove them with the correct sized spark plug socket.

UPDATE
Have finished with it for now! I put everything back together, the spark plugs seemed difficult to get out, so they must have been in fine. Maybe one isn't working right?
Would it be worth replacing them, as they seem fairly clean considering?

Don't take this the wrong way but as this is your first car and you don't know what to look for my advice would be take it to a local garage and get them to check over it for you. But as they do it ask them to explain and show you. That way you learn at the same time do next time you know what your looking at.

Thanks mate. I have a friend who works for a well established garage down here. He pulled out all of the spark plugs and said they looked fine. he cleaned them off with a wire brush and re-inserted them. He seems to believe that the coil pack is on its way out. Would this be likely?
