Im Issues After New Crankps And Camsps Installs

[papernpaste]

History: Frick and Frack installed a new Long Block in my 2001 Astro in Nov of '09 at 97K miles. I now have 104K miles on it.

Within a month of the install, I started getting IM codes setting. One was Crank Shaft Sensor (can't recall the number) and the other was P0335- Crank Shaft Position Sensor. Over a period of months (delays due to lack of funds), the engine has a minor "shutter" or "miss" AND I, intermittently, get a "thump" thorugh the whole drive train (like a dead miss),usually around 45-65 mph. I had the trans checked- "A OKay." I replaced the Crank Position Sensor near the Balancer because it was the least expensive. That was about three months ago. This past weekend, a friend helped me replace the CSPS. With a couple of tries, we were able to set the distributor in place, just to insure that it was installed in a position that would make it operable. The timing seems to be right... starts immediately and "purr's like a kitten." BUT, I still have the intermittent shuttering, usually when there is a slight load on the drive train, and it is still manifesting that "dead miss" issue AND it is still throwing the P0335 code. Any ideas-suggestions? Thanks
