[QUOTE="DOWNS, post: 438885, member: 21038"] For what it's worth, the distributor has the Camshaft position sensor in it. Honestly, there's no good way to test either the CKPS or CPS without an oscilloscope. Something most people aren't equipped with. If you run into a similar problem in the future then and exhausted all over troubleshooting options then sometimes the best option is to throw a part at it as much as I hate doing that. Also RE: battery and ground cables. I've had cable that looked perfect externally but when cut open they were basically a tube of corroded copper. If the maintenance history of the cables is unknown, it's usually best to just replace them and then replace them on a set schedule from there on out. I do mine every 5 years or on first purchase. Given all the sensors are on a 5V reference, even a somewhat sketchy ground can have your values all screwed up going into the computer. [/QUOTE]
