Thank you, I myself expect it to be the crankshaft position sensor. I am going to start on that project on Friday 4 30 10 so that way I have 3 days before I have to drive it to work. Also plan on doing the timing chain then too since I can hear it slapping against the housing at idle (ticking) and then go away when i push the throttle down a little. Any tips are always welcome. I wonder why the crankPS only acts up when it's warm. Mmm
