Australian Car Repair Issues? Ask an Auto Mechanic for Answers ASAP
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.
you're welcome. please let me know how things turn out.
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.
the egr valve was installed in the zj 4.0 in 93. so you may not have it. what is the build date?
it will be on the plate on the door jamb i believe
so its a 93
it should have an egr then
anything built after july of the presnt year is actually the next years model
keep me posted.
