Cadillac DeVille Check Engine Light due to EGR control solenoid/valve failure
Cadillac DeVille Problem
Average Mileage: 133,427 mi (58,500 mi - 175,000 mi)
didn't have a check engine light nor a service soon light, but car did start to run rough at start up, but once warm it ran fine. Checked codes and got E-48, E-49 and E-52. Checked the throttle body and cleaned it.Checked EGR valve and found out it was good and that one of the hoses was cracked. Replaced all little hoses and cleared codes. Car started to improve...acceleration and idle. No codes have appeared since then, but it would be in the best interest of the car to just replace the EGR valve and check all hoses to make sure you don't have a vacuum leak.
