1998 Buick LeSabre Custom 3.8L MIL Lamp on
Help This one has got me chasing my tail. The long term fuel trim data shows 149. Vehicle runs great no complaints on runability from the owner , his only complaint is the check engine lite on. I have run the fuel system pressure test from alldata all seems ok...
