EF Surging on idle
Hey guys, just replaced the Harmonic Balancer or Crankshaft Pulley on my EF & the engine has started surging, on idle it will idle from 400rpm up to 1300rpm & has stalled twice out of about 10 starts.
Iv checked all hoses etc that i came near for the job, everything is the way it should be. I understand the timing is changed electronically so i assume it cant be that? Engine doesn't lack power or run rough while driving, only at idle speed. I have JMM Dev5 installed, the cam has always been alittle rough but never like this theres deff a prob & think this is probably related to the crankshaft pulley.
