Lost with the VW Polo

Bueenas
well, I tell you (I don't know why it seems to me that we already know each other, hehe, the web is a handkerchief)

I first have to clarify that mine is a pole of 86, to carburetor and with quite simple electronica. That is, no on -board computers . The most complex I think it will be the hall sensor of the ofco.
On the other hand, it is true that the problem I had with my car is very similar to the one you have, Santicl. I tell you what I have done trying to solve the problem: change of cover of theco, pipe, coil, cleaning of the gasoline tank, cleaning everything I could, including battery terminals and motor to chassis, change of the contact dice ...

of all this, which surely helped solve my problem was cleaning of the gas tank (there was a lot of shit) and change of the coil (in my case I should be quite cascade). With this, now the car goes very well as far as possible.
In my case there was no problem with the acceleration body, and tempoerrature sensor, because I do not have (or if I have, but I do not think it is able to stop the engine. The most will be contained some look on the board). The land cables, clean them, to rule out ...
I don't know. I have some links that are sure to interest you, but now I am short of time. I post them as soon as I can.

Greetings
PD: If the car is 99, the problems started at 5 months, how long are you taking the nightmare ,?
