Paul – you are so sad in your argument. The fact is that an ice core from Antarctica shows the last time carbon was so high in the atmosphere was eight hundred thousand years ago (800,000) and errors such as you have cited are sort of like a doctors error when he says you have lung cancer and will die in six months. Woops he made a mistake. You lived a few months longer or died a few months sooner. But you die. Doctors have falsified their degrees and still managed to perform surgery. Others have real degrees and killed patients. One has to look at the overall benefits of doctors and medicine and not say well they used to leech patients so how can we trust them or that guy wasn’t a doctor even though he saved patients. An ounce of prevention is worth a pound of cheap gas and a cheap car.

Sounds like a timing problem. Have a mechanic reset the timing. If that doesn't cure the problem, examine the plugs. One or two of the plugs might have corrosion on the electrode and they're not exploding gas properly. If the plugs have oil on them, you might want to take the vehicle back to "the nice guy."
