Oil on a clutch will do it, and a clutch that's been overheated will judder too. A clutch that's not been heated adequately can judder, sometimes slipping it carefully will smooth it out.

lp

It should be clearer from this illustration, they go through the back of the valve cover on the non-VTEC and the front on the VTEC as shown.

Faulty Injector or timing

If the injector is not spraying correctly you will be burning neat diesel out of the exhaust.

The effect of one cylinder missing will make the judder

If you bought it from a dealer take it back if you bought it off the street find a good fitter

YOu need to check the clutch master cylinder and the slave.
Sometimes the seal roll in then.
When that happens it's like riding the clutch.

timing belt!!

sensor needs replacement or ABS module
