Rewa25DeT Posted May 20, 2017 Share Posted May 20, 2017 Sounds like rod knock ?? Hey guys. My r33 gts25t is playing up. Was converted from auto to manual and runs the factory TK auto ecu. It was running out of power at higher revs (approximately 4500-5000rpm) as the VCT wasn't working since the VCT needs the auto in drive so it will switch on. So i connected the TJ manual ecu and VCT starts working. The next day the car started misfiring at start up so i change it back to the old auto ecu. Still misfiring. Now it feels like its running on 5 cylinders most of the time and sometimes 6 cylinders. While on 5 cylinders it has a knock coming from the firewall end but on 6 cylinders nothing. I replaced injectors, spark plugs, coil packs, fuel pump. Any advice please thanks Link to comment https://www.sau.com.au/forums/topic/470496-sounds-like-rod-knock-%3F%3F/ Share on other sites More sharing options...
89CAL Posted May 20, 2017 Share Posted May 20, 2017 Well you need to work out what is causing the misfire/cylinder drop out. If it is only making the noise when its playing up, it could just be a simple issueDoes it misfire randomly or is easy to make it happen?
