Engine is hard to start?

Hello,

I have seen the engine coolant temperature sensor cause this issue not reading correctly while giving the computer a false reading. You can get a scanner to see what the reading is cold to see if it is close to outside temperature to confirm the issue. here's a guide to help and the coolant sensor location so you can check it out:

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

The sensor may not give a code, the P0449, P0442, P0445 are EVAP codes which wont affect the engine running. Have we serviced the throttle body latey? if not this guide can help you:

A scanner is a good idea for anyone that owns a car, you can use it all almost every car out there.

Sorry, I missed that in the first post. A vacuum leak will cause hard starting also, I would look into the coolant sensor as well, what happens is the sensor range gets off a little (not enough to give a code) but enough to cause engine problems. Did you clear the codes once the new parts were installed?
