Intermittently car will seem to short out for split seconds. If I let it idle all is ok but as I apply the gas the split second short comes back. This can happen at various speeds and sometimes if I go over some bumps all becomes ok. Friend with a madza3 had similar problem hat was fixed by changing the solenoid.
