intermittently I've noticed my engine light coming on when driving.today it finally said I had codes on start up. So I plugged in my diagnostic tool

Lmao these work perfect for connecting terminal 1&2 together to get your code readout through the engine light.
I came back with 3 codes before they repeated

15 & 33 both of which I think must be in there from when it was apart replacing the fuel pump.
And 15 (interactive muffler control)
So I went fishing under the airbox cover and found it wasnt working.
