Extreme idle

Good on doing the service work.:cheesy:
Now to the troubleshooting.
A failing CPS , when cold may yield good readings, when warm to hot, it will cause the engine not to run.
A failing O2 sensor, the lambda unit, will trigger a CEL and the MPG will drop. The engine will continue to run, as the ECU will go into default.
The MAP ? I do not know.
We do seem to have a weak spark.:eek:
