Symptoms of a Bad Intercooler Buy Auto Parts

+

· Symptoms of a Damaged Intercooler. A leak in the intercooler lines will fail to supply the required amount of air under the optimal pressure, thereby affecting the airfuel ratio of the engine. This will either cause the engine to run rich or lean. If the engine runs under a rich condition, the excess fuel will be expelled with the exhaust gases.
