2010 Chevrolet Traverse - RPM issues after changing injectors

My RPM is fluctuating after changing the fuel injectors, anyone has same problem?

A failed injector o-ring seal could cause that. Wandering rpm is often caused by air leaks, unwanted and unmetered air getting into the engine. So check everything that could cause that for leaks

  • idle air control gadgetry
  • air path between air filter and throttle body
  • anything connected to intake manifold (egr, pcv, brake booster)
  • check for exhaust system leaks

Sometimes spraying starter spray in suspect areas will cause the rpm to speed up. If so, you’ve found a good clue about where the leak is.
