Has anyone experienced this?

On Wednesday I noticed at at a stop, my car was idling low. To the point where I thought the engine had shut off. There was also a slight shutter feeling when coming to a full stop. Similar to what it feels like when your AC compressor shuts off. I didnt think much of it because the car felt normal while in motion.

On Thursday the problem was still there, however my car now took 3 tries to start up. It would turn over just fine, but immediately just die. I tried this a few times over the course of the day. Sometimes it would start up and stay on, other times it would take 3 tries.

There were no flickering / dim lights. I tested the battery and its fine. I dont think it has anything to do with the electrical system.
There are no CELs

Anyone know whats going on? TIA

 

I have this from time to time as well (6MT) and I have not a clue. I think its a fluctuation is oil pressure to be honest. One of the times it happened my oil light came on, another the car was almost due for an oil change and I was on an angle in a parking space. I started the car and it immediately shut off. I started it again...same thing, so the 3rd time I started it I hit the throttle a little and it was fine. So for me and my situation, I think its a drop in oil pressure

 

How does the car feel when its idling, like at a red light. Does it feel like the motor shut off or something?

 

mass air flow sensor dirty or dirty throttle body?

Ive had similar thing happen before I cleaned throttle body, car wouldnt start on first try while I left it off a parking lot for 30 minutes, took few cranks before it did. After cleaning TB's never had this problem again.

 

Thanks for the advice. I went ahead and cleaned my throttle bodies. So far there werent any failed starts. Idle seems to be okay at a dead stop. However, sometimes the rpms do move up and down slightly by themselves. Could be just the ecu relearning. Im keeping my fingers crossed.
