Code 34

12-30-2023, 05:28 PM

Every-time, I think I have the problem solved the code 34 pops up. Yes, I have changed out the Mass Air Flow Sensor and make sure the screen is clean and clear of dust. Is it a possibility that the cause is the Mass Air Flow Relay? Appreciate some help., this code is driving me crazy/.

Make sure all vacuum lines don’t have a leak and the TB gasket is not leaking. You can check the vacuum with a gauge should be 20-22. Does it run rough?
