Fiat Palio Nafta Monopunto accelerates alone.

Hello beautiful people of this forum.
I have a motor racing workshop and I am new on the issue of electronic injection.
I am having a problem with a Fiat Palio Nafta 1.6 with monopunto injection.
They brought it to me because the engine was bad, it was hard to start and failed and failed crazy.
Repair start and verify that all the mechanisms that work with empty were punctured and sucks air by there.
As if that were not enough, the Lambda probe did not work for having the cables cut.

Now start and go, but it accelerates thoroughly when it heats.
I thought it was the step by step, check and it doesn't work well.
Now, if I disconnect the MAP sensor, slow down and work well.
I thought he was the, although his departure was and was almost value.
Change it to a new one and follow the problem.
Now I have it without Map sensor, although it is relatively well, I stain the Ollin's floor at the exhaust outlet.
Signal that is burning a lot of fuel.

I have to tell you that the engine is not right, smokes through the vent that connects to the admission.
I cannot test it with Scanner, I have the LM327 that has served me with several cars but this Fiat has three pins card instead of the MDD.
And I understand that the LM327 does not work for this model no matter how much the adapter has.
Thank you very much.

Hello, good day, check that it does not los about gasoline by the injector o. The background 4.48 volts thus check if the other would be.

Hello, first of all, thanks for the help.
Check the butterfly sensor and I was dirty, I gave you with spray oil and now gives a good sign.
Regulating this in 0.99 volts and accelerated 4.6 volts.
Change the injector orings and improve a lot.
Now when he heats and walks in a march he is going well, when he stepped on the clutch and let it run without a march he accelerates slightly and lower the rpm.
This does it repeatedly type four or five times and then it is regulating well.
Now I took out the admission's vent hose because it smokes a lot and is like drowning the engine a little.
Stop now is working with the MAP connected and does not smoke anymore for the escape.
Before he smiled a lot and left black spots on the floor around the escape.
Tomorrow in cold I try another you see. Since thank you for the help.
