Good night to the people of the forum. I am from Ecuador and I have the following problem. Vehicle turns on very well, normal relapse, after the 92 95 degrees operating temperature reaches the relay, it rises to 1500 rpm. It is then lowered to 900 or 1000 then it is maintained and can do it throughout the day. I have tested IAC, TPS, ECT valve, ground wiring correction, resolved unions in the cable maso, has scanned and when the failure happens, no error code appears. The data line is monitored and rpm rpm is observed or low, normal ect, and other sensors within range, MAP sensor indicates a slight increase in motor vacuum (it is new). Please if someone has any idea of the origin of the fault or better yet to give me a suggestion would be very grateful ...
