Car Stalls at Idle

Do not throw parts at it. Read the manuals. Learn to diagnose properly.

Perfect. Thanks!

Edit: By the way, that crack in the pipe is just on the inlet to the sound generator tubing leading to the firewall. It won't make a difference at all to the operation of the fuel system since it's before both the air filter and MAF sensor.

Perfect. This gives me options. The more the better.

Thanks for the info on the cracked pipe. I see some people get rid of it and plug it at the firewall and at the air filter. I might re-glue it just for peace of mind.

Device ordered. I like the smart on/off feature. It’ll be nice to see live coolant and engine oil temps especially with summer approaching.

The MX+ has arrived! I’m going to get it paired up. Any suggestions for apps or data logging that might be beneficial to the issue I’m experiencing?

.

MX+ is working after doing a factory reset and pairing it up to iPhone. Customer service recommended pairing it with iPhon. Not sure why.

What live data would be beneficial to post on here?
I’m not getting a reading from O2 Sensor 1.

sound deadening and some thermal insulation i guess

Any suggestions for data logging?

Thoughts on no readings on O2 Sensor 1?

Today the engine was stalling every time I went to stop. After following the engine idle re-learn (instructions posted on this forum) it no longer stalls and idles much better.

one of two things most definitely: Heat soak or fuel system.

You need a live full log. upload to datazap.

Thanks. Here's a link for a data log.

Not quite enough info with that log?

what are you using to log?
Log as many parameters as possible
Anyway I had something similar not too long ago..
Was driving me crazy..
Long story short, it was the Fuel Pump (or could be the regulator) for me.
i was kinda having the issue prior to me replacing the fuel pump..but it gets worse after replacing it..but apparently i didn't install it properly.
I just replaced the whole fuel pump assembly with a new pump. I took the opportunity to upgrade the pump.

Car will start fine and then stall after a while out of no where , it starts right back up ..
But then gradually get worse in which i have to wait like 5 to 20 minutes before it starts again.
The longer it goes the shorter it stays on and the longer the cranking.

You can easily test the fuel pressure by getting a fuel pressure/vacuum tester, unplug one of the Low pressure fuel line (preferrable the one closer to oil filter, plug in to the fuel pressure test.. Put the car into ON position without starting the car. You should see the pressure build up and stay at least or above 35 to 40 psi ( i think can't remember).

keep it that way for like 5 minutes or so to make sure the pressure isn't dropping..

Using OBDLinkMX+ and the app specifically for it. There are probably around 100 SAE PIDS to choose from. I selected 26 in the log I posted, but I guess not all apply to my car or theyÂ’re limited to some makes and models?

Suggestions from you or anyone on which SAE PIDS to select? Screenshots of selected PIDS while in the app might be easiest to show?

I went through your thread. My car has never experienced any difficulties starting back up after stalling. When I stored it for 6 months, I did remove the battery. I had it tested before re-installing. I was instructed to re-install the battery, start it up and let it idle for 30 mins then drive it home. I let it idle for about 25 mins, backed the car out of the unit, got out to close the unitÂ’s door and it stalled. It started right back up, but stalled several times on the drive home. It would start back up and I was able to keep it from stalling by pressing the accelerator and keeping it around 1,200 - 1,500 rpms.

When I recently did the idle re-learn procedure, I could hear the throttle body adjusting/moving or whatever and it hasnÂ’t stalled since. Perhaps I should clean the throttle body and do the idle re-learn again?

The car is stock other than an Invidia Gemini R400 Dual Tip Catback Exhaust, a hard wired radar detector and a starlight headliner - all installed by previous owner. I never use the headliner. IÂ’ve noticed while driving at night, sometimes the headliner will light up for a split second. Almost like thereÂ’s a power surge? Seem to notice it on hard acceleration.

I would like to do some more data logging regardless.

Even without cranking issue, it could still be a fuel pump issue but now that I think about it, it could also be related to a failing alternator.
I have ecutek so I can't really thoroughly help you with the PID.
Are you tuned?
