I just installed a set of 80# injectors into 2006 I5 Colorado and am having a little issue. the truck runs good overall, except for the fact that holding the throttle steady anywhere between 1200rpm to 2000rpm the truck stumbles slightly. It revs fine, idles great, but has a stumble in the low load/low rpm area. I am running these same injectors on my 2007 I5 and were able to dial them in just fine with no issues. Take note mine is a 3.7l vs. the 3.5l 2006. There isnt a wideband on the truck yet so I cant utilize that data currently. any help would be great.
