Hello all i started up the car tonight and began to drive off, has i stopped at a stop sign the revs stayed at about 2100 rpm than dropped off as i continued to drive it revved and drove normally i stopped and checked the CEL which has been on for a while do to a cat code, but now there are two codes. P040 and P1518. the car has been revving higher than usual lately but not lie this, usually only a couple hundred higher at idle than back to normal after a few minutes after driving. please help this is my daily driver and i needs it to al least sort of work.

one more thing i have mixed and matched O2 sensors bosch for the front and OEM for the back, been meaning to get that fixed but keep putting it off,, is this my cars way of telling me to pay attention?

The P1518 has to do with your IMRC (Intake Manifold Runner Control) malfunctioning. Check for a broken actuating arm.
You P040 isn't a valid DTC code. Needs to be four numbers.
