I've had this issue for the past year. It will go away and pop up again. This last time it was gone for 500 miles.

My car has 105k miles.

I've fixed every leak that was found and have had several people smoke test it. The last test from the dealership showed the air intake tube was leaking, but that still didn't fix it. I've put on a new fuel pump as well, and replaced the O2 sensor twice (warrantied one out just in case

The only possible things I can think of at this point are the Mass Air Flow Sensor (which has been cleaned) or the catalytic converter. Gas mileage seems about normal, the car says 23.7 mpg
.
There is a slight smell from the exhaust.
Any advice is greatly appreciated, as this has been a huge headache this year.

Guitarist01, was it your low pressure pump that was replaced or the high pressure pump?

With how much you've had done and no codes for the converter or MAF, I would suspect something else, maybe a leaking injector.
