Strange Noise

Probably just the vacuum lines/brake booster sucking in air after you shut down, might have a small leak in a vacuum line somewhere

That’s my best guess

[fringe karma]

yea its coming from inside the intake

i think its probably a bad intake manifold gasket

i think its causing this small misfire

[limber spear]

Typically excess air past the MAF just causes a lean condition as it shouldn’t affect the valve timing but

It could idk

Would have to actually look at the engine to properly diagnose it

[fringe karma]

the map sensor?

[fringe karma]

i already checked and its clean i tried plugging it in and out and that doesnt change anything

Mass airflow sensor

It’s apart of the air intake system, it tells the computer how much fuel to spray in relation to how much air the engine is sucking in, so you get the proper air fuel ratio for complete combustion. If you get an air leak after the sensor the engine doesn’t know it’s getting too much air so it won’t spray enough fuel to get good combustion. This is a lean condition. Rich condition would be too much fuel not enough air.

yes i just got it replaced actually

most likely a leak somewhere

i somtimes hear it spray when it tries dying on start
