Glad to hear things have worked out well for you. I bought my 2007 h3 in. Nov. I love it!! Best vehicle I have had. I have also had the feeling it may stall but it never has. Thanks to this forum I know what I need to do to fix. I also get the TPM warning. Tire pressure is fine. My wife has an Acura TL and gets the same warning all the time. Seems like it is a very fussy sensor.

 

Sweet they replaced the head!

 

Remember the TPM's in each tire I believe run on batteries (I think if I'm wrong please correct me) so if it's cold it may effect the battery current and also the tire pressure itself will be lower due to the cold. If the TPM is on all the time then either fill your tires or one if the batteries might be dead. I believe they are in the valve stems. (Again correct me if I'm wrong. Thx. )
