QuestionI have a 1992 Cadillac Deville and recently the Check Engine Soon light came on. It is giving the codes E40, E85, and E70. It seems like when I apply my foot to the accelerator that it seems like it is trying to accelerate, but is having difficulty. Kind of like it is "bogging" down. What should would look for to repair and is it okay to drive until fixed?
AnswerE40 is a power steering switch problem.
E85 means that you need to service the throttle body.
E70 means that you have an intermittent TPS.
You need to fix all these codes.
I would NOT drive the vehicle until these are fixed.
I can provide pictures and directives for you to fix these problems. Contact me at: onlineautohelp@msn.com
