There she is a little dirty.. Still had the idle problem,So here is what I did,and I need yalls input on the solution I used..

Set the throttle stop in a little,then adjusted the TPS to where it read 0%,and it idles fine,works good into drive etc.. The problem is that I can only achieve 97% WOT now.. I havent driven it much yet cause its not legal yet,But it seems a little under powered.. Is there a difference in 3100 and 3400 TPS's??

Let me know thanks

So you are holding the plate open more to get it to idle, yet adjusted the tps so it reads 0% at this point? And the TPS will only read 97% at WOT because of that. It shouldn't be a big deal because like 70% or something it goes into power enrichment mode and I think from that point to 100% it's all the same to the ECM. The plate will still be open at 100% though so no worries on that.

Less power is probably due to less lift than the stock cam has. Or the ECM needs time to re-learn the fuel trims, even stock engines will need some time and improve with driving around a while normally.

Ok new problem,unplugged the oxy sensor,and the IAT, started it several times,and drove around on surface streets,then a short run on the interstate,and the computer never threw a code,and there are no codes stored or pending... Bad ecm??
