So my car keeps stalling on me as if its running out of gas. It seems to like to do it on bumpy roads, when I make a hard turn, or on hills. I've installed a new fuel pump and I'm using ryancb's maf and it still does it. Its doesn't happen all the time. It will go for w week with out a problem then it will start up again. I unplugged the maf and it works fine now but I need to figure out what is causing this before I push it off a cliff. Any ideas on what might be causing it to stall?

 

I need some clarification here, do you mean you unplugged it and re plugged it in? I would start with checking all the electrical connections especially the crank and cam sensors, if they are loose a bump could cause an intermittent connection and the car would most definately stall.

 

I've checked all them but ill check them again and no I drove with it unplugged halfway to work and all the way back. The mechanic at the dealership siad that I'm plugging it makes the ecu run in a open loop instead of closed. which bypass is a lot of the sensors, I don't know which ones but you said it does and it seems to work. I'll check all the plugs for sensors in the morning and give it a go

 

Interesting. I cant unplug my maf the car wont barely run if I do that it. Definately wont idle and I would have to work the clutch just to keep it going. You try disconnecting the battery to reset the ecu?

 

make sure its on in the right direction
