I have 2004 chev trailblazer, 4.2 L and check engine light on constantly. I brought to mech & he got a code 4 the air pump cct. (not sure code #) He said all he could do with it was check the relay & it checked ok! I would have to bring it to a dealer. Also when its cold it idles's poorly sometimes stalling or reving to high @ stoplights. Could these 2 problems be related? Any advice would be appreciated.

I answered you yesterday over in the other thread you asked about this.

The air pump issue is not related to the idle problem. There is a How to article in the "Articles" pull down menu about cleaning your throttle body, which is an easy, do it yourself project. If you own tools. And don't mind getting your hands dirty.

The air pump we could help your mechanic fix, if he came and asked for the schematic, or if you did a search on P0410. You really need to know the exact code to get exact advice.

My best advice: trust my advice and stop asking in multiple forums shopping for a better answer.
