An 02 reg with the D7F engine.. Could be one or more of the following..
1: Defective spark plugs.. There is a date code punched onto the side of the Champion plugs.. ie 2b, 3d etc.. If the plug is dated lower than 4G then there is a solution that states that all the plugs must be replaced.. It can cause poor spark and/or interference and spikes on the injection computer. (it is also recommended to reprogram the injection computer, although dealer only)
.. Requires removal and cleaning the butterfly/body..
.. Replacement only, and is a fairly common problem.
4: Defective upper engine loom.. Replacement with modified loom.. Known problem and pretty common..
.. Known problem, not very common
6: Water ingress into injection computer loom connectors. Particularly the righthand side one.. Fix is to replace the upper engine loom and injection computer..
7: Incorrect valve clearances.. Commonish problem.. Fix is to remove rocker cover and reset them..
