I had a general tech question. I have heard this said, but wanted to know more info on it. If you have check engine light than your car is running in limp mode? Is that correct, meaning your car is not performing its best so that you don't go reving and breaking things. If this is true than would vtec still kick in? Would your rpm be limited say from 8000 to like 6700. What are some other affects?
