hi there my problem is this . my clutch was leaking fluid from underneath the car i managed to fix the problem.. so after that i washed the car at work with degreaser and pressure washered it off. drove it home fine.. got back in it a couple of hours later it started up fine then after about a hundred yards it started to sound like its running on 4-5 cylinders. so the problem is this . when i first start it up its fine but wheh driven a few 100 yards back to burbling noise and its not running on all cylinders . anyone any ideas what may have got wet or damp..???

It is very possible you got some water in the spark plug wells. Remove the plastic cover on the top of the motor and you will see the six coils. If there is water down in the wells where the coils go, it needs to be removed. Repost if this situation does not get resolved.
