Engine stalls after ~10 seconds

Battery is 4 years old, but the car cranks just fine. Engine sounds fine for the ~10 seconds is runs, then it just dies. I've only put on ~15K miles in the 3.5 years I've had the car. Had a 60K miles service done 3 years ago, so the fuel filter should still be good. Spark plugs and wires were changed just after I got the car. I'm not getting any CELs, even checked it with my scanner anyways, but no codes.

 

Of course I'm having car problems when the wife is dogsitting at her parent's house. :mad:

There's this small metal box with 4 metal lines coming out of it on top, it sits of right in front of the air filter box. I checked the air filter, it's still pretty clean. Could I have knocked something lose when I put the air filter box back together? The MAF sensor is still connected.

 

Where can I get some engine diagrams? I have no idea where the idle bypass or vacuum lines are.

Did notice a hissing sound. Sounds like its coming from the left side of the engine, can't really pinpoint it when the engine only runs for 10 seconds.

yep. i bet that's it. if it wont run or stay idling, even with some throttle blipping, its totally disconnected, and should be pretty visible

 

i had that damn thing pop off while i was driving. not fun

 

you might try this if you must search with your ears...

 

disconnect the wires from the maf

the car will figure that the maf is bunk and enter limp mode

 

fix your problem

 

reconnect maf

 

reset ecu or have autozone clear your codes or whatever

Turns out it was the vacuum hose that connects to the bottom of the air intake, just after the MAF sensor.

Somehow it came loose when I was checking the air filter.

I figured as much. Same thing happened to me when I installed my new intake. Car started up and ran fine the first time. Turned it off and tried again...stalled. Took a look under the hood and that was the problem. Glad you got it fixed.
