Greetings all. I recently purchased a 1999 GT convertible from a friend to restore / tinker with since I recently retired. I'm currently re-doing the inside... carpet etc. I'm the fifth owner of the pony and it has 186K miles on it. I do not know how many after market parts are on it. My next project is to soup up the engine but I don't have a clue what throttle body I have. How do I determine this with out taking everything off and start looking for part numbers etc? What was the stock throttle body for a 1999 GT? I don't know if it helps but my VIN is 1FAFP45X3XF106166. Also, what would be the best upgrade for the overall engine performance? I have read that if you get to big of a throttle body it could actually degrade engine performance due to too much oxygen and not enough fuel. Any information would be greatly appreciated.
Thank you,
