We have a 98 Durango, 5.2 with 180k on it. It runs great, just recently tuned it up. New plugs/wires,cap/rotor, cleaned TB, replaced IAC and the TPS, cleaned the MAF. Only problem is that once in a while on the highway it will stall or sputter for just a second. Kinda like everything just quits, but it's just for a second.It hasn't happened to me more than a couple times and I hardly noticed it. Felt like hitting a bump in the highway. It has happened to my wife several times when she's driving it. She thought it was going to be time to put it down the other day. I drove it, and of course, It did nothing wrong. Any ideas? Thanks!

 

Maybe the throttle position sensor.

 

I am trying to remember if I changed the TPS or cleaned it. I think I tried cleaning the old one and then put a new one on. It's been about a year ago. That would make sense though. Just not sure if it would be bad already?

 

They go randomly. I'd just do it since it's only 35-40 bucks so you're not out too bad if it isn't the problem.
