crown vic rear end problems can anybody help

Dont know why rear end out of 07 crown victoria has my 06 crown victoria driving different any suggestion. Check engine lights on now along with little wrench symbol on dash and car seems to lose power around 45mph but does not turn off still accelerates but a round 45 is when little wrench symbol shows up and then seems as if it loses torque or acceleration power

I'm not an expert but I did have to have the rear end on my 09 Crown Vic rebuilt being a former officer I know how we treated the vehicles and some drove very hard. My car was former C.H.P. which meant most of the miles were highway. The rear ends in the Interceptors are setup low off the line but faster at high speeds.

You error codes on the dash lights my seem to indicate it needs maintenance. I would check with your local Ford dealer if these particular light come on with either the mass are flow sensor or O2 sensor needs replacing.
Good Luck,

You need to have the codes checked. Autozone will check it at no charge. Then you can go from there.
