Hi I just brought a 02 Gtp, 133k on it, runs beautifully... except 2 things. When the car is warm it idles just above 500 rpms, it's not a rough idle either, quite smooth. The 2nd problem is when the car is cold and I go out to warm it up, I start it up and it make a ticking /clunking noise like someones tapping on an empty pringles can with a screw driver, after it warms up it disappears, and it's random not clockwork like the rpms. Any advice will be helpful, I want to avoid all major cost due to this being my first big purchase and having a carnote.
