starting issues after car sits for a while

[blue62]

Cris,
Have you tried reclibrating your E-gas (throttle)?????
To see if it helps your hard starting when hot issue???
It's a long shot but easy to do.

I do really think it is an EVAP issue.
Perhaps when the mechanic removed the intake he did something to the EVAP hoses valves or connections. Hoses and some valves for the EVAP are right there.

If you want to give recalibrating the E-gas a shot, this is what you do.
Disconnect the battery for a few minutes so the ECU drops the E-gas calibration settings.
Reconnect the battery.
Turn the ignition to the on position "do not start the car"
Do not touch the gas pedal.
Let it set that way for at least 1 minute.
Turn key off for at least 10 seconds.
Start car.
Thats all there is to it.
