The Amigo is a 5 speed 6 cylinder. I am having an issue with the car shutting off while turned on. When I turn the car on it idles at lower RPMs than normal and I often have to push the accelerator to keep the RPMs up so the engine doesn't shut off. I cannot shift from 2nd or 3rd gear to neutral and roll to a stop without the car turning off. Once I get to a stop sign I must rev the engine and keep the RPMs up to keep the car from shutting down. I have tried cleaning around the battery and securing connections on the battery. The battery is two and a half years old. I think this is a battery issue or possibly a gas line issue. What do you think the problem is?
