have about 50000km on the odo..using 91ron gas which is recommended for the hr15 engine. there is a pinging noise at low rpms or when going uphill.
i changed my plugs using the original plugs and same problem so changed to the original plug but a colder version of the plug and same problem.
cleaned injectors, throttle body and same problem.
tried a higher octant fuel and same problems. not sure what to do again. any ideas are welcomed
