96 4runner having trouble starting only when cold

[toyoma05]

hi, im new here, well i got a 96 4runner that is just having a hard time starting up only when its cold, but when i finally get it started, it idles low at 500 rpm. when it warms up, i can shut it off and start it back up with no problems. i pulled this codes of it, p0115 which is the ECT sensor, and p0505 which has to do with the air idle control valve. i already cleaned the valve, the tb. but still has a hard time to start. i thought it would be the fuel pump and the fuel filter,(which i already replaced new), but still has the same problem. im thinking of replacing the ECT sensor tomorrow. but help me out please, your help would greatly be appreciated.

Replace the ECT sensor and that should resolve your problem.
