Question about 1999 Mercury Cougar
Just bought this car a week ago had bad gas leak when you filled it. would wake up in the morning to a gas puddle. this morning check engine light came on husband took it to the shop to have gas leak fixed and they tested the car and came up with these codes p0453 p1519 b1318 b1342 b1201 b1756 car runs fine ???
Generally this happens because these codes were reset at a dealership etc. These problems should have been corrected before the codes were reset (reputable dealer). A common reason that these codes come on is because of excess hydrocarbon emmissions with a misfire. If this was a temporary event, the light would reset. Since it continues, another likely reason is the oxygen sensor in the exhaust system has failed.

In fixing this code, it is quite common for people to just replace the EGR valve only to have the OBD code return. The EGR valve is not always the culprit.
