I have a 2002 corolla that at idle runs great, starts great but at 1500 to 2000 rpms has rattle noise in top end. Higher rpms rattle goes away. I have replaced timing chain and tensioner, variable timing valve, lower end has been replaced with all pistons and rings bearings and compression is solid all accross. I puller the timing actuator and seems fine. I have no engine codes but the rattle is still there at mid range rpm. Any thoughts?
