Hey guys i bought my z about 5 months ago most of that time it has been sitting there due to waiting for a steering rack from brytech for 4 months. Anyway on topic every week i start it up and let it run for 10-15mins i noticed a rattle a few weeks ago and decided to find out wat it was turns out it was an exhaust bolt that was missing and causing the metal cover to move and rattle. After putting a bolt in to hold it i start the car no rattle then out of no where the idle goes up and down and eventually stalls its now doing it every time i start it reving it keeps it from stalling im pretty sure putting that bolt in could not have caused this problem. Also this is my first car so my mechanical knowledge is limited so be gentle any help would be greatly appreciated =D
