I've reread this whole thread 2x. People keep suggesting the same items to you:

- 1st have codes read. We can help better if we know what the computer is seeing as the fault
- Check PCM soldering and resolder or replace if it's bad
- Check for a vacuum leak, possibly under the throttle body

One question, did you replace the CPS with an OEM Bosch one? I know people have had terrible luck with the others. FWIW, the CPS was the problem with mine when I had very random/intermittant problems with idle and starting.
