I have a rare 92/93 ZJ with Drumbreaks and it stalls after

Customer Question

Hi, I have a rare 92/93 ZJ with Drumbreaks and it stalls after idleing so I can drive - but when I stop at the lights it will stall 8 out of 10 time when I try to continue to drive
JA: Is the check engine light on? Does the car stall at idle or when driving?
Customer: it stalls in the transition from idleing to driving check engine light is on and off -
JA: What is the model of your '92 Jeep?
Customer: 92 it was the very very first ZJ
JA: Are you hoping to fix this yourself? What have you tried so far?
Customer: I cleaned ground I cleaded fuses and relay connectors My current Idea is it is the IAC being dirty
JA: Anything else you think the mechanic should know?
Customer: no that's all

Hi Im David ,thanks for visiting the site. Your idea of cleaning the iac is an excellent start for sure. I would also suggest to remove and clean the egr valve and its passages. Also clean the throttle plate inside the throttle body. Another known problem that can cause your issue is a weak battery or loose and corroded terminals.

Customer: replied 3 months ago.
Ok, the battery terminals have exchanged allready - and the battery starts very well and has nice voltages - Thank you for your advice to focus on the throttle part of things

a 4.0 doesn't have an EGR Valve only V8 if I understand correctly
Expert:  david craig replied 3 months ago.

let me look up that info. egr were installed on alot of jeeps, but the 4.0 mfi wasnt one of them for that year.

Expert:  david craig replied 3 months ago.

the egr valve was installed in the zj 4.0 in 93. so you may not have it. what is the build date?

Customer: replied 3 months ago.
where can I find it?
Customer: replied 3 months ago.
My car has an AW4 and Drumbreaks - so it is one of the very early MY92/93 cars
Expert:  david craig replied 3 months ago.
