Stalling and service 4wd switch

[ETXXJ89]

OK so today I was sitting at a red light I started to go and it bogged down on me badly I double tapped the skinny pedal and it got up and went but then it started displaying a service 4wd switch message. Any clue what that means? It's a 95 zj( grand cherokee) with the 318 v8 auto trans and NP249 transfer case. It's been stalling in reverse and occasionally at low speeds taking off, what you think clean IAC sensor? What about the service 4wd switch message

cleaning the IAC never hurts, but I'm thinking you might need to replace the TPS. Some of the other guys on here might have a better idea than myself though.

I think TPS too. That service 4WD is to get you to take it in for dealer service

Had the same message on my moms '93 ZJ, never had any problems so we never put forth the effort to find out what it means. :P

Yeah don't think I'm gonna worry about it more worried about the stalling
