I want to know if my car will be expensive to fix. The problem it failed on is, exhaust carbon monoxide content after 2nd idle.

This could mean the trole bore is dirty and needs service. Here is a guide to help you clean the throttle bore, also the engine needs to be tuned up if it has not been done recently. Once other thing is a vacuum leak which the test should be done when the engine is cold. Here are three guides to help us fix the problem:
