all i can suggest is that you remove the electrical connectors one at a time and spray wd40 or a smear of grease in to the connector and reconnect the plug do this on all of them that you can see and see how you go from there i think doing this will resolve your problem this includes under the bonnet and in the car connectors that you can see

i would replace engine control relay and earth straps on the chassis legs to engine mounts. a dodgy connection on these earths cause an all mighty headache for the tekkie and makes the car behave very badly. hope this helps
