2004 Cadillac DeVille Base 8 Cyl 4.6L
Engine lights on and when in drive the car shakes except when in neutral?? Also check coolint is on check it good
The guy I bought it from told me it needs spark plugs that's why it pulls and shakes but it could be more.
First thing is to have the check engine light scanned . Could be many things . Get the codes and let us know what they are .
