'87 Coupe DeVille 100,000 miles
E40 code is present. Possibly a bad connection or faulty switch. If the code is being set because of heavy steering pressure and not from a switch problem, what might cause the 'heavy' pressure? I've not noticed any difference in steering, so I'm wondering if bleeding the rack/pinion and new fluid would help?What is the best way to bleed the system? Would just a 'gravity' bleed work? Thanks for any advice/help with this.........
