[QUOTE="TimberTim, post: 436511, member: 20208"] Don't discount this possibility ! take your coil off and shake it. Mine rattled and I replaced it. Also I haven't seen anyone suggest checking Vaccum , If you don't have a gauge..... take a picture of the throttle body where all the Vaccum lines connect. Leave the fuel pressure regulator and the MAP connected ,plug off all the ports on the throttle ( golf tees work good for this ) If it runs better connect the lines back up until it starts cutting out again. A quick version of this test would be to disconnect and plug off the hose that goes to the PCV Valve, it could be plugged up.....Good Luck [/QUOTE]
