I see that my car after let it run for 30 minutes started to have problems, first it star to shake then the rpm gauge drops lower than 7 hundred and the battery light turn on y after that the car die but if a press the gas pedal it runs ok what can i do or check?
I sugeest you open up the distributor and make sure that ALL the wires connected to the Ignition Module is fitting snugly onto each of the terminals. The BLUE wire is normally the RPM connection. Also see if the terminals on the outside of the Distributor are clean and making good contact. If needed you can unplug the socket, spray it clean with Carburettor Cleaner and lubricate it with normal Vaseline (Petroleum Jelly). Follow the Wiring Harness to the Fire Wall and do the same with the other Connecting Sockets. Hopefully this will solve your problem.

Hi Rodrigo, The idle control is activated by the temperature sender unit. It sounds as though yours is giving a cold signal to the computer and it pushes up the idle speed to compensate as if it has just started. The sender unit is a different unit from that which operates the gauge on the dash instrument panel. Replace it and I believe your problems will be over.Regards John
Could be the VANOS Seals. You can buy them for 60.00 and it takes about 5 hours to do (but will save you a lot of money). Follow the steps at this site and you're good to go: http://www.beisansystems.com/
Change your coolant temperature sensor for the computer.(not the one for the temperature gauge).They are located one beside the other,under the distributor cap.The parts supplier will know which one you need.When you start the car cold it usually idles 1800 to 2000 rpm for a minute or so and as the resistance starts to decrease,the rpm drops.after a couple minutes the rpm goes to 1000 rpm.People that are in the habit of driving the car right away at 2000 rpm are putting a huge stress on the axles,and find that they are replacing them every 100000 km.It also wears out your brakes faster .When the sensor goes bad,it causes a fluctuating idle .
It's the choke doing tis job. It reduces the amount of air to the engine to help it start/warm up. As the engine reaches a good operating temp it will drop the RPM's. Some times they do get stuck, so some cleaner wouldn't hurt. Spray it into the throttle body while the engine is running. Also the O2 sensor could be bad.
