Ford Mondeo accelerates alone

Hello everyone, I have a 1.8 16V injection mondeo of the year 94 The problem is that when it gives it it is hot at night in hot cold he only accelerates and puts at 2,500 and up to 3,500 rpm, I have been with the accelerator regulator for a while, the one that is in the butterfly box, disconnected, when I have had it disconnected does not accelerate but it gives me.

I think it can be the TPS, I need more details please :)

Tell me what information you need and try to collect it, a doubt that is the TPS, thanks.

The TPS \ "Position of the throttle butterfly position \" and the other that can be failing the YAC valve that controls the slowdown, I would be interested to know what is the sensor that you disconnect. To get an idea of ​​what it can be.

Ahh one more thing the TPS is the one that goes in the throttle butterfly is a black box usually. greetings
