Consult IAC Ford Ranger Dohc 2.3

Hello, I write from Chile, I have a Ford Ranger 2007 2.3 dohc, 125,000 km, it happens that in the morning, the truck when starting lights 900 rpm, sometimes it turns on normally and in others I have to accelerate it to turn on, buy a new IAC, disconnect the battery, install it, when you turn on the truck the revolutions went up to 3,500 rpm, and Disconnect the IAC connector with the engine running and there was no change, continue to 3,500 rpm, install the valve that the truck had and walk normally, during the day it behaves well, only sometimes gives somewhat longer starts but in the morning I have the problem for its ignition, I would appreciate an answer, greetings.

Hahahajaj friend do not scare yourself, you must put the new IAC valve, then disconnect the negative batteries about 30 seconds, and then connect it, then you open and close the contact at intervals of 15 seconds, about 3 to 4 times and start, you will see how it regulates well.

Hello, thanks for your answer, I will do it and I tell you how it went, greetings ...

Hello, Insale the new IAC, it happens that the one they sold to me was for 2.3 but model 94, install the one that corresponded but I continue with the problems, in the morning part to 1500 or sometimes at 900 rpm, and after a few seconds it begins to ocile the acceleration rises low, then it is normalized, in the day in occasions it gives starts longer than normal, it will be the TPS? greetings..

From what you say it can be more problem of the engine coolant temperature sensor or air in the engine coolant system. Eye that the air filter also gives a similar failure.
