I’ve got this srt4 been running good got my Diablo tune spot on this summer having no issues, but here recently it’s been having a random hesitation I’ll be cruising or gradually getting up to speed about 2,000 to 2,500 rpm’s and it will hesitate feeling like a misfire only for a moment my afr jumps from normal 14.7 to 16 or 17 and bounces right back in a moment. Very occasional random, My tune was set perfectly and now also if I go wot instead of being 11.5 11.7 I’m lingering staying in the 12 area on afr so I’m thinking my fuel pump is getting weak or filter or regulator clogged. I changed plugs again hadn’t been but maybe a couple months since I changed them before all was fine before. I’ve checked some wiring all looking pretty good but I did notice these plugs are all laying over in the fender well I have cai and everything has been running great until now so I don’t think these plugs are my problem, but I do have the battery temperature code and another code for one of these plugs not sure how important they are as everything was running great before and they’ve been unplugged since I got the car I bought it that way. Just curious if someone could teach me if I need these hooked up or not it appears this car has a 2003 ecu since the car is 2005 and I’m getting the battery temperature code thanks.

Like you speculated, I would investigate fuel issues first. Ignition issues normally cause rich conditions. A lean condition indicates not enough fuel.

I have a whole new pump filter and regulator assembly I’ll be putting in this weekend, hoping that fixes the intermittent hesitation.

The p1190 code resistor out of range is something I also have there is no sensor in this plug tan plug in pictures how important is that , it was running fine before without it.🤷‍♂️

Could be a TPS problem?
I had the same problem regarding the battery light, having an 05 😕. I just found the battery temp sensor and put a resistor in it, problem fixed. Hope that helps!
