Release the Cancel button once the LED lights come on. This resets both the printer and the NVRAM together. Press and hold the Reset button near the back of a 5P or 6P printer as you turn on the power. Holding it for less than 20 seconds resets the printer only.
Once the throttle body is exposed, spray the throttle-body cleaner inside the air duct, and use the brushes to gently dislodge the dirt, gum and varnish that are present. Note: Be very careful not to let the thin, plastic spray nozzle (or anything else!) fall into the throttle-body opening.
What is a throttle body and what does it do? What happens if you continue to drive with a damaged one? My engine light came on and the dealer said they cleaned my throttle body and reset the engine light but if it comes back on then I will have to replace the throttle body. I have a long distance move coming up, is it safe to drive my car on this move? What does a throttle body do anyway?
