Check Engine Light on Due to Failure of Secondary Air Injection Pump

2003 Cadillac Seville Reviews

bought my 03 sls used with 100K and no engine leaks at all. Beautiful car with all options. Only Problem is a leaking transaxle seal on the drivers side, that really dumps it out when in reverse. Love this car has more power than you'll ever need. So I'm going to pay the 1,400 to fix the seal. To me it'll be worth it.
