Default Intermitting idle fluctuating and stalling issues

Hello
I got a 1997 dodge ram 1500 5.2l and when engine is cold sometimes when i get on and off throttle the idle drops rereally low like250 and picks up and sometimes keeps droppi g to 0 and even dies .

When at operating temp it drives fine most the time but somwtimessomwtimes surges at light throttle at speeds higher tham 40. Let idle stops or get on it it stops..
Idles surges up and down at 250 and 500. And at 1000 but just fluctuates a hair

Cleaned tb and new tps and iac reset computer with no luck no check engine light and all problems are Intermitting. Not sure wer3 to look next ne3d to get scanner with live data

WWill make some videos to better show symptoms

What brand IAC? Our trucks really don't care for aftermarket parts in critical locations.....

Like heyyou said, our trucks are pretty picky with the aftermarket sensors. They seem to be hit or miss. When I had my 97 1500 I went through 3 aftermarket IAC solenoid before I finally just went to a Chrysler dealer and bought a oem molar one. My symptoms were identical to yours and the molar solenoid solved the issue

That was a bad plan. Using cheap sensors only invites mysterious problems.......

If you can return both and take a trip to your nearest Chrysler dealer. Get mopar brand sensors. Your old sensors cleaned would probably be better than those new cheap ones.
