Strange electric problems
 

My car has started doing weird things. When I turn the key so that the power is on, the idle speed valve makes the noises (opens and closes few times) as it usually does, but sometimes it goes berzerk -> injectors spray fuel and the tacho meter jumps to ~1000rpm :roll: The car starts always and runs fine. Has anybody had same sorts of problems? I removed the fusebox and soldered it, but it didn't help. I have measured the Ecu grounding points but they seem to be ok (maybe I have to check them again). I'm wondering if something is wrong with my Ecu or the engine loom.

more than likely water i the multiplugs near the coil which connect the car lom to the engine loom, notice how well placed they are to get rained on directly below the bonnet vent - nice :)

they are allways a favourite to cause all sorts of wired goings on, best bet is to chop them out and solder each wire directly with some heat shrink over each joint then tape the lot together.....

Thanks. I'll check those connectors if they are ok.

The problem causer was that multiplug :top: :banana: I'm so happy. Now the car works perfect again :content: It was like you said, water had gone in to it and it was oxidized. I chopped it off and soldered the wires. Thank you very much for the help. :clap:
