Just curious, I don't have a problem with mine idling but I was curious to see what your guys blazers idle at? When I first bought it i didn't pay attention but when I installed the flowmaster 40 muffler and for the first start of the day (very first start) it does 1000rpm. Now with my FIPK by k&n it does 1100rpm <--(so freaking loud with that baby). And than calms down to about 700-900rpm. I'm just curious and wanted to start a new thread (i hope its new). Thanks!

 

About 600 rpm @ idle.

 

900 for me

 

when mines cold its about 1grand, then wen warm it drops to about 500

 

my 91, cold 1150,warm 650,in gear 500,backseat with the girl=the valves float!

 

About 600 rpm

 

cold @ 1000 warm @ 650 in gear @ 500

 

800 cold, 550 warm, 500 in gear

 

Cold 1000 warm 650 in gear 550-600. It's a 2000 ZR2 blazer.

 

So mine also does 500rpm (i didnt mention) when it has been driven around for 3 or 4 times.

However, does anyone, whos blazer idles at 500, does it seem like it is on (like running) when it is at 500? I was at a stop light one day with my sister and it was doing 400-500 and I looked at her (the music was way down too) and said "is my truck on?" I had to check the key, open the door, and put it in reverse/drive just to make sure because it was soooooooo quiet!
