My car keeps stalling all of a sudden. It was fine all day, but when I went to start my car tonight it stalled. Started it again, then another stall. Sounds like it could be a throttle body problem? I decide I should go get some TB cleaner and take care of it tonight, even though it's low 30s right now, but I couldn't even get out of my apartment complex cause anytime I let off the gas, it stalled. Anybody have any thoughts? Is it probably a dirty TB? Can I clean the TB's without dedicated TB cleaner? BTW, no CEL or anything.

Edit: 7at, checked all fluids and everything is good there.

 

Does it run normally otherwise? A leak in the intake tract between the airflow sensor and manifold could cause it not to idle. Check your intake hoses, particularly if you have an aftermarket intake.

 

Stock intake. Replaced the air filters a couple weeks ago, but it hasn't had any problems until tonight. I'll probably have it towed to infiniti in the morning. I don't really want to check the TBs in this 30 degree weather.

 

Yeah, there is a lot of things it could be besides that. I would at least do a quick visual check to make sure both mass airflow sensors are plugged in and the intake piping is in place and isn't obviously disconnected. None of that should have been touched to change the air filters. Take advantage of the warranty, roadside assistance, and loaner car if you have it.

 

I've got 2000 miles/5 months left on the bumper to bumper warranty. I guess the timing of this actually isn't too bad.

 

I had similar issues... my car would stall at cold start, and sometimes even when the engine is at Temp.

I did TB cleaning and MAF sensor cleaning as well. fixed the problem ever since.

I'd suggest you do this every once a year, or every 10,000. I do mine every Spring-summer.
It's simple task, I have no experience with cars, just with basic knowledge, anyone can do it.

BTW, you can directly spray TB solution inside, just don't over spray it. MAKE sure your car is cooled down as well. I'd suggest you get this done ASAP! it would solve your problem

 

Update. After not being able to drive my car on thursday night at all, I decided to get it towed to the dealer on friday morning. I try to start it again friday am, same issues. Call to get it towed, flatbed shows up and my car starts right up with no issues. I drive to the dealer to get them to take a look at it. I showed them a video I took, and they immediately said the idle air learn procedure needs to be done, but they have no loaners available. Scheduled an appointment for monday morning.

So 99% chance it will be dirty TBs, but just in case it's something else, they'll be able to tell me. I would have cleaned them myself, but didn't have any cleaner and it was cold as fawk that night. If they try to charge me to clean them, I'll just tell them no and do it next weekend.
