SHORT PROBLEM IN FORD KA MODEL 2005 ENGINE R

Hello, I have a problem with a Mod 2005 Ford Ka with Rocam 1000 engine. The fault I have is that being in idle and thorough floor makes a nod, a remained as it would be in a carbure car that did not walk the pique pump, and every so often throws an against explosion, as if due to lack of gasoline at that time. I had little pressure, more precisely 1.8 bar in idle and 2.5 in full load or drawing the regulator's vacuum maguer Well, the butterfly body and butterfly sensor, the butterfly sensor tried it with the multimeter and gives 0.90V in idle and goes gradual until it reaches 5V. Probate the MAP and give me 1.3-1.4 in idle and 3.8 to 4.1 in full load. And continue the fault.

Hello, I recommend reviewing the IAC censor, its seal, and cavities of the base of this censor, also check the connection and its cables since these are departed or cut internally and is working with the computer memory signal.

The IAC valve is an actuator not a sensor, and my in idle regulates well, it is only when Ecello suddenly ..
