HELP I bought a VW Corrado 1.8 16v 1993 with a bust engine. After total engine rebuild I did not know about electrical faults i.e fuse box in a mess and a few loose wires under the bonnet - 1. Black wire beside the fuel distributor which switches fan on if it comes into contact with the body or the engine, even if the ignition is off.
- Blue and white wire from distributor loom is not attached, Haynes manual has it on a temperature sender but a red and green wire and a red and yellow wire is attached to both sensors beside the warm up valve. Car has been driving well, then suddenly engine becomes difficult, sometimes impossible to accelorate when engine is warm, the rev counter flickers up and down irratically, the engine stalls while driving and backfires. Also the oil cooler feels very hot. This problem seems to go as mysteriously as it appears, everything seems fine, then it comes back again. HELP Anyone with any idea of whats going on here.
