[2fast4u]

i have one trouble code and its p1133. i dont know wat this is and how do i fix it? thanks

insufficient switching, do you have headers? That's a fairly common code with headers.

Reset the PCM or if you have autotap etc. clear the code. Details of your car?

[2fast4u]

no headers stock basically slp lid cold air package and descreened maf I also got p1153

what it the switching bank if this code is on will my car run slower?

Is it not the rear o2 sensor? Dont think the rear 02 will effect performance. Either replace or get o2 sims.

1133 and 1153 is insufficient switching on both banks, both front 02s. Don't know if descreening the MAF is the cause.
