what sensor

[darknessofay]

im having trouble starting up when the engine is cold? what sensor controls the fuel to air mixture when the engine is cold, it seems the injectors are reall messed up or its not getting the right mixture to get it running. thanks. ( 1.8 SOHC, no mods )

mixture sensor...?

You should start by the very basics:
When was the last time you replace your fuel filter?
Do you often use Injector cleaner additives?
Have you checked your ignition timing lately to be correct?
Are your spark plugs correclty gapped and burning fine? no misfiring?
Your Spark Plug Wires are in good condition? no cracks/rips or such?
When was the last time you changed your Cap and Rotor?

Im almost certain that your problem can be fixed by a simple tune up. Check all of this and let us know.

Coolant temperature sensor has the biggest affect on your fuel mixture before closed loop.
