Like many others, I was experiencing a miss under load at low RPMs. It would usually do it when I'd roll the throtle on in 6th gear.

Before I FINALLY replaced the EGR, I replaced the plugs, wires, replaced my header gaskets, new 02s, new LT4 KM and even the intake elbow. None of these changes improved the condition.

So, I changed the EGR and it runs great... for now

I am one happy guy

 

How much do they go for? I'll have to keep that in mind....

 

Mine ran $50 shipped from gmpartsdirect.com

I know most of the time a miss is caused by ingnition problems, in my case it was the EGR. Go figure
