Will it hurt to drive my car with the check engine light on?

Question

When test was run the code P1518 came up.

Answer 1

P1518 Intake manifold runner control (IMRC)

This is for the IMRC whcih the rod tends to break off, due to its clips wearing out, The purpose of the CK ENG LT is to protect the catalytic convertor and the catalytic convertor is to protect the enviroment from harmful emission emitted into the atmoshpere, that a automobile produces, And for the vehicle to maintain fuel control. Whenever the CK ENG LT comes on you are emitted higher amout of emission, P1518 is so minute in drivability that it takes a ECM (vehicle computer) just to inform you of a emission problem. This type of code will not hurt the engine in anyway.What will force you to make repair for this is your emission test, in order for the registration. the CK ENG LT will fail in the emission test area.
