October 22, 20187 yr Is this something I should be worried about? Car fluctuates revs at idle like a high strung diesel would. RPM on gauge doesn’t move, drives normal though
October 22, 20187 yr scan for pending codes live data might help any oil on the plug wire boots? when it's idling, try squirting a small amount of starting fluid in the intake - if it smooths out, could be (???) dirty throttle body or IACV issue. If it gets worse....?bad injector?......misfire or ? hope others with more experience reply Edited October 22, 20187 yr by 1 Lucky Texan
