Dodge Ram Rough Idle but runs perfect?

[Tim S]

I have a 1995 dodge ram 2500 V10 4x4. It has the 47re transmission. In stop and go traffic it has a weird idle issue where it idles fine, then when you just every so slightly tap the gas it dips from 600rpm to 200rpm then slowly climbs back up to normal. This is really annoying in stop and go traffic and especially with the AC on, but happens regardless of AC. Other than that issue, it runs like a dream. No miss fires or anything. Any questions, just ask!

Throttle position sensor and idle air control valve are the usual suspects. I'd be leaning towards a slow to react tps

Thanks for the response, it is becoming such a pain in stop and go traffic. Soon to get it fixed.
