www.alldata.com - it's $25 for a year-long subscription and gives you troubleshooting charts, parts diagrams, exploded diagrams of every system on the car, etc - it's an online factory service manual. Excellent resource that is well worth the small cost.

I was going to say crank sensor, but you changed it. What have you done to it latley? Or did this just start? I kinda want to say PCM for some reason. Any welding done on the car latley?
