Re: 4.6 L cold am weather wont start Grand Marquis 06
You have electronic fuel injection, you shouldn't have to touch the pedal. Have you checked for codes? I'm wondering if it's an issue with the MAF, by pushing the pedal, you're opening the throttle body and allowing a higher air flow past it. Along with checking for codes, try cleaning the sensor and see if it improves.
Ever notice that there's so many high performance parts available for GM products?
Did you ever think that maybe they NEED them?
