I have a 1995 Geo Metro 1.3 L. It starts fine, usually idles good. As soon as I put it in gear it's like it loads up and has NO power and usually stalls. I have tried changing the plugs, cap and rotor, fuel filter and map sensor. Nothing has made a difference. I'm at a loss and am getting frusterated. HELP please! Oh also removed the cat and replaced the rest of the exhaust.
