It should be pretty easy, thats why there no "directions" Lift up the hood, now at the headlights there should be 2 rods, lift these rods and the lights should lift out, to access the bulbs.

locks have so many key positions but on a popular vehicle this can happen where they have the same key indentations ,but yopu friend couldnt start your car as it has a chipped key ,but years ago in the car rental we had two fiat puntos parked in the same car park in torrevieja and they got taken by the wrong persons so we had to drive around and find the houses and get the cars back and swop them over .but this was before chipped keys ,also had it with two ford fiestas in benidorm as well

I investigated this for over an hour while tossing things around in my head and truly think that you need to have your O2 censor checked along with your converter. One probable cause to your misfire could very well stem from your catalytic converter due to an O2 faulty etc.etc. Why not try a smog shop before tearing that engine apart any further and replacing any unnecessary gaskets. Thats a tight engine in my opinion and unless you really mistreat it, I would bet on it at race day. Have you recently been in a fender bender? Let us know cause that might change my advice.
