Further information. I carried out a compression test on the vehicle and found the compression on cylinder 1 to be down.

my corsa runs lumpy on tick over (hot and cold). Runs better when the revs are increase to 2500 and above. Fault codes are P0300 - random mulfiple misfire, Also showing codes P0301 - P0304, misfire cylinder 1-4.
I've replace the plugs and coil pack but its just the same.
Next Ive...
