Hey guys, i have a 98 gtp and about a month ago i noticed oil spots under my car and some oil coming from my intake. I replaced the PCV valve and the major oil leak from my pan was due to the gasket on plug was gone. i still have a minor leak and now there's some odd vibrations at idle about 50% of the time when i start the car but go away when i put it in gear. there is the occasional hard start too. Other peoples advice would be much appreciated.
thanks
