I changed the spark plugs then the wires an it still has a misfire then my o2 sensor came out my car is riding real rough now what should I do

 

Still... means plugs and wires did not fix it, I am guessing...Any repairs prior to misfire?Check condition of distributor cap and rotor for corrosion or contamination(oil). Disconnect EGR valve vac hose ? Make sure EGR valve is not stuck open(up). Check for vacuum leaks. Are both injectors spraying? If you have spark tester does it indicate enough spark?

 

My 94 cadillac fleetwood brougham. The interior lights do not shut off when all dores are closed, they stay on constantly. I took all 4 dores apart and disconnected all the harnesses and put the fuse back in and all the interior lights were still on. Anyone know the problem or what to look for? Also replaced the time delay relay and still no progress and also checked the headlight switch and that was fine as well. Any help? Thank you.
