For almost a year I have been getting a check engine light for P2187 only to find out that the hose coming from the brake booster that runs under vacuum pump was cracked. It was really hard to see until you touch it, it slips right off. So I decided to replace all the hoses associated with the vacuum with the spullen silicone hoses and man what a difference it made. The hose's fit but I had to put a good amount of elbow grease on to get them to properly fit and i also had to buy another set of clamps cause the ones that come with it were to tight. Besides that the car runs better now.
