I have a 2007 H3 with 115,000 miles on it. I've owned for 9 years. My problem has only occurred a few times since I've owned it and lasts a few days to a couple of weeks then goes away. I did read a thread done in 2019 about an owner with the same problem. I didn't see where he actually found the cause. If anyone has had this stalling problem and knows the cause please reply. I'm thinking it might be a moisture problem but not sure.

 

Start simple
-Clean MAF (MAF cleaner only)
-Clean throttle body (carb cleaner or TB cleaner)
-Make sure the intake fasteners are tight (they sometimes vibrate loose)

 

Welcome. I MOVED this out of the H3 FAQ section because this is NOT and FAQ and that sections tells newbs to NOT post in it.

Look at this thread that sums up what to do.... modern day version of the "tune up"............ Acts like it wants to stall/rough idle -No CEL -What To Do:

 

Thank you. I'll try the recomended procedures you attached. I Apologize for posting in FAQ.

 

Scan pcm and post ALL DTC's & HDTC's.

 

Dont forget to look at the small curvy hose under the intake resonator box. If dry rotted will cause problems.
Change spark plugs and coils with the oem stuff NOT crap chinaezium stuff.
