Re: lost all low end power?!?
You really need to deal with the DTC's that are turning on the CES light. You indicated that it was a knock sensor code. In the future you should post the trouble code numbers.
The knock sensor/s will send a signal to the VCM to retard the ignition timing in the event of a sensor malfunction and/or actual knock or "pinging" (pre-ignition).
As to the previous replies, they are all good ideas. But deal with one issue at a time. The 1st one being the current active fault that is turning on the CES light.
Do a search for "knock sensor" or something similar . There are several posts in the main forum that address this issue.
