Chevrolet Optra has me crazy

Hello friends, I have a problem with a Chevrolet Optra Double Cams Axis Motor 1.6 has the same engine as a Daewoo Nubira II, the problem is as follows: With the cold engine it starts but when accelerating it does not accelerate it is kept in idle and sometimes when accelerating it thoroughly when it does not accelerate some petarders occur once they have passed a few minutes it is fixed and accelerates well but sometimes when it is. and indicated TP (TPS) and crankshaft position sensor, the complete acceleration body and the crankshaft sensor were changed, the result does the same problem and the scanner marks code P0171 and ignition coil changed the coil, the scanner marks me without error codes and makes exactly the same problem and it has me crazy

That such a friend
the first and more difficult is to keep calm and the
second is to analyze the problem
1; the TPS did you programs it with the Scaner when installing it? So
that the CPU of the vheiculo and the

caliber
2

is requested
. They properly plug in luck and talk any novelty

Did you check the tuning? If coil indicates from the crankshaft position sensor to the same spark plugs, and reset the computer Aver if the failure is removed.

Hello friends, thank you for your opinions, unfortunately I continue with the problem, we change the spark plug cables, I check the point of the distribution belt (even take it out and put it again, keeping the direction of turn in the belt) I do not mark errors unless you disconnect any sensor appears in the scanner, the fault is accentuated with the cold engine when it rapidly accelerated it, it does not accelerate it. Accelerates, with the hot engine it works well but when driving and trying to run it is missing I have doubts with the MAP, the fuel pump and the camshaft sensor "I do not know what you think"

Hello friend, although I do not know that model it is possible that it derives from the Opel line.
I tell you what happened to a colleague friend with a Corsa, it turns out that the crankshaft pulley that in turn makes of phonic pulley, is of stamped sheet, and what happened to him is that he delayed in the accommodation of the crankshaft, which ran delaying the point of the rotation sensor, check it, lost by lost, since the fault you describe is similar to that of my friend.
I don't know if it's a great contribution, but in these cases everything is useful.
