Hello all, I decided to go buy a Vacuum Pump at a dealer shop parts that comes with the O-ring for $169.00 today. Also will buy NGK Iridium spark plug for $15.00 for a set of 4, Engine and Cabin Air Filters to replace and buy those at either Autozone/O'Reillys or Napa auto parts. My co-worker friend told me that we should install all of these parts in 30-45 minutes at my work place parking lot. Now for the leak for my Air Conditioning unit; I think i can get by because my A/C is working fine and don't know of any noticable leaks. I wondering from some in here if the line is loose and needs adjusting/tightening to fix the minute leak; I'll youtube it to see if I can do it myself or have a local mechanic do it for me for much lower than $728.00.
