1997 Grand Prix GTP Supercharge - On a 'cold start' she powers when starting ignition, revs go up as normal, levels down to idle speed but then 'pluffs' out (dies). She used to start after 3 goes but it's getting tougher to get her to fire without giving her gas to warm her up. What might be the prob? I hear that it can't be a choke as she has no carb...fuel injected...but wont there be a butterfly in there for air/fuel flow? Could it be the ECM sensor? Just want to have an idea, as a female, before taking her into a mechanic and maybe getting swindled...lol Thanks for any help!
