When using the directions to clean the EGR intake is it necessary to have the car on? I saw one comment stating that you don't. If you do, where a bouts is the throttle in the engine so I can raise idle manually? otherwise it is stalling. third question, which I guess should have been my first, is it normal to have some suction in to the engine from the EGR and still have the CEL issue or is my problem likely elsewhere and if so what could that problem be?

Thanks for any help.

Great response! Thanks everyone! n/m I figured it out myself.
