Coming out exhaust..car cut of the other day..why can it b?

coolant level keeps coming up low when it is full temp. normal could it be the sending unit in the reservoir

cold air on passenger side when it should hot

tried pushing the open and lock button on the driver door several times

When the horn is actuated with horn pad or panic button,it won't shut off without restarting car or pulling the relay. The relay can then be reinserted and horn does not blow until the horn pad is actuated again. press it again and the horn continues to blow until I repeat the process. Tried new relay.

Driver side blow out cold,other blow out hot air when i have the heat on.

I have replaced tires, struts and shocks, front end aligned, tires balanced. Car drives fine until @ 63 mph until @ 75 mph and then a significant vibration. It lessens after 75 mph but does not go away. It is not noticeable below 63 mph. Car has @ 110,000 miles on the odemeter. Thanks

After the car starts and dies it will start back but will not keep idling, the shop can not find the problem. Will the injectors cause this to happen? They have checked all the normal things that could cause this to happen. One thing I noticed before the problem started the mpg was sometimes good and sometimes bad. Could this be a clue to where the problem is at?

When turn off they will not return to their place of origin. They will stay in the same place before going off.

Happens all the time

I had it scanned and these are the codes P0102, P0107, P0134, P0300, P0403 and P1107.And I forgot 2 new parts I replaced both Oxygen Sensors.
