Does the car have a button on the shifter handle somewhere to disable overdrive? Also, there is a plug on the transmission that must be plugged in to engage overdrive so check to make sure it is plugged in correctly.

screwed up relay or crossed wires..

if they do fold down reach in with a coathanger to reach the releases.. if not.. they bolt in and cant be removed from the trunk side as they were installed from the inside.. but a slim jim can open the car.. call law enforcement and they will come by and open it for you..especially if there is an issue like your child locked inside(or your dog)..

If it is an aftermarket sensor try a factory sensor. Lots of problems with Chinese parts.

Depends. What car is it, year model and everything? Car/truck/suv? The vehicle turning over because of you using the starter doesn't mean that it's running or even getting spark. The obvious question is does it have gas? If it does have fuel but it's not reaching the engine, it is more than likely the fuel pump. Fuel pumps can go out without any warning but I really need to know what type of vehicle before I can really give any help.

I had the same problem along with a rough idle and found out it was my EVAP canister.

this is the code for your speed sensor replace accordingly and then when fixed clear codes and test to see if code pops up again

check he trimming belt may have jump time

If you are getting this code, go have your charging system checked. it's likely that your alternator is bad, or the belt that drives it, or the battery itself is bad. If you have a battery that is NOT maintenance free make sure the water is filled. P0560 means that the ECU is sensing that the charging system is failing to charge the battery and therefore is providing low voltage throughout the entire vehicle.

Sounds like your throttle is sticking try cleaning your throttle body and plate. Could also be a sensor issue. Any codes. Possibly a vacuum leak

Sounds like you need to replace your fuel filter or fuel pump if its going bad.

This filter should be inline possibly near driver side of car underneath (of course)

semms to be like some of the vapor lines coming from thank to engine might be flooding your engine,
but also locate the fuel pressure regulator at the engine compartment and unplud the vacium hose, if you see any fuel coming out from fuel pressure regulator, or if the vacium hose smeel like fuel, then the regulator is not good.

intake leak, bad plugs, pre cat oxygen sensor. take to kia and have them run full diagnostics. Most likely pre cat oxy sensor or bad plugs and wires.
