the older cars with the 3.0's have always had issues. For starters go over your crank cases hoses and check them all by pulling the tip off the head cover likely will be sludgy as hell. Also look for signs of breaks. The crank cases hoses always break in these cars after a few years and cause idle and running issues. after that look for a little computer think its called an ignition control unit should be 1 for each side of the engine likely located on a air box. this modual will often go after a 150,000 km or so. It will cause miss fires and shakes as well as not running condition. Would be a good thing to change the fuel filter while your at it as well no telling what the previous owner put in it for fuel.

After i just changed the plugs and ignition coils the codes it showing now are intake air temp sensor to high signal and cam...g301 g300 g164
