ANSWER: Hello Cezar, What year Astra? the newer ones have an electronic throttle and you may have damaged it, on the other hand if it is an earlier model you may have dislodged the throttle linkage. You would have to have a mechanic check i to know what to look for. Check the accelerator cable (if applicable) - Good luck - Paul

QUESTION: is a 2000 model and the last 3 days was crazy sometimes is working perfectly and then suddenly it stops, and accelerate itself again if is a an electronic throttle where is the damage located . please help.

Answer
Hello Cezar, if the throttle is electronic, the damage would be in  the actuator (black box bolted to the side of the throttle housing) if there is a cable going to the side of the throttle housing then it is NOT an electronic throttle. - good luck-Paul
