Stall issue...
 
Hi everyone, Hi everyone new member here. I just purchased a 2007 hummer H3 base and really love it. The only problem I have is, sometimes when I’m at Low speeds usually when I’m braking, the engine shutters and sometimes stalls and dies. I throw it in neutral and itstarts right back up and takes does fine after accelerating . Any ideas for more experienced members?

Thanks in advance :)

How many miles on it?

Every fuel injected late model vehicle need to have its Throttle Body and MAF sensor cleaned. When was the last time yours was done?

Another thing to check is spark plugs and coil packs, they can make your idle real rough and stall out

Here is the exhaustive list of items to look at with a false stall and/or rough idle in the H3 FAQ section (please do not post in that thread): https://www.hummerforums.com/forum/h...what-do-33916/
