Hi, I have a problem with my PUG... When I push accelerator pedal in the idle, sometimes I have detonation in intake manifold of the engine. My mechanic and car electrician, dosen't know what could be a problem!? I have change spark plugs (putt new EYQUEM with three branches), new EYQUEM cable, new O2 sensor and I have done the complete service (oil, all filters, all belts...). Can any one tell me what is the problem with my car or instruct me to do tests in order to discover what the problem is!?
Thank's!!!
