The Curb

I know this isn't very Cougarish...

Nicole's 2013 Honda Fit has shown engine light often,
sometimes flashing when running and solid when idle.
It also stalls when cold (no super cold temps yet)

3 trips and over 350$ later at the dealer: NO CODES. each time, no engine light seen.

I'm thinking of buying a Bluetooth odb2 adapter/reader and a "torque" app for phones to see the codes that don't register and anything else that could help.
any suggestions, ideas?

now looking at https://www.amazon.ca/Bluetooth-Diagnostic-Scanner-iPhone-Android/dp/B07LD6X3F7/ref=sr_1_10?dchild=1&keywords=ELM327&qid=1607102567&sr=8-10

I have a cabled ODBD-II reader that I picked up from Harbor Freight. It has paid for itself many times over. The BT version looks nice - no cable in the way. Does it read 'live'? A few times I have had to had mine hooked up and reading while I went down the road in order for the problem to crop up and a code to appear.

yes, it reads live which i think would see the codes that disappear when at the dealer

well, i got this

and i got this
https://www.amazon.ca/Cartman-12V-Battery-Alternator-Tester/dp/B00EXIEVO6/ref=sr_1_1?dchild=1&keywords=Cartman+12V+Car+Battery+%26+Alternator+Tester&qid=1608209838&s=hi&sr=1-1-catcorr

the app to read is free for torque basic and 4.99 for full app. This available for Android, IOS or windoze.
I think the problem might be due to my using battery tender "recond" too often on the cars. It seems that repair hits at almost 16 volts where:
normal is at 14.4volts
cold conditions (for -41F) is at 14.7 volts
repair is at 15.7volts.
since we are now at 3 visits to the garage for no result, i am changing the battery for the best (biggest) available for a Honda Fit 2013. Please note the best battery for a Honda is still ridiculously small: 465 amps.
This is limited to a battery bay that could fit 4 times in a normal car battery size

how cool is that!
Nicole can't get her Iphone to pair with the OBD2 reader, but my Google pix2 (Android) paired with no problem.
The car has not showed an engine light but my phone with the free Torque app picked a P0304 code which is a cylinder 4 misfire. At least, we know what it is (and it seems to be a common problem for the car) .
It's always good to know the engine won't blast it's way out through the hood.

previous repair was a split coil boot on cylinder 4. (had all kinds of oxidation at both end connectors from water getting in) and really bad plugs on cylinders 3 and 4
The honda place in Amos had charged over 250$ for checking the plugs, which they didn't do!!!
The Honda place in Val D'Or spotted the problem right away.
BTW: to inspect/change spark plugs on a 2013 Honda Fit: They are between the engine and the firewall. You need to remove everything on top, including wipers!!!

Now have a p0303-p0304 code, leading to injector problem.
Whichever Ninjaneer dropout came up with that idea is FIT to be tied...
back to Val D'Or again today
