so i went to fix my broken water thermosensor today, basically to get at the wires i had to take the whole intake off (to the point where you can get at all the injectors.) i hooked everything back up after i was done, cannot see ANYthing that i missed, and now the car starts, and then dies right away. does not make a difference if my foot is on the gas or not. is not my alarm- i put it in valet mode. any other ideas?

edit- should also add that i have triple checked all vacuum hoses... but still let me know about any ones you think i might have missed!

man if i can only get a look at it i might be something as simple as a fuse or vacuum leak in the manifold, did you break the old gaskit? use a new one? use sealant?

Check the connection at the afm. If the afm is dead/disconnected this is what the car will do.

which gasket? i just used the old one, same as i did when we put the motor in after the rebuild.

and yeah, from what i've read, it looks like it is gonna be an afm issue, or i have vacuum escaping somewhere after the afm... i'll have to look at it tomorrow, it's pitch black out right now. looks like i'm drivin the sunfire to work tho

Take a pic of the engine bay for us. Preferably in higher resolution and focusing more on the AFM area, it was an s4 though. One of my friends had a similar problem and it turned out the AFM was upside down. Also maybe its a huge vacuum leak. Possibly one of your intake manifold gaskets. That would definetly cause this to happen. Also check for cracks in your TID.

Tid? and i don't have any hi-res camera at home right now

chwkrx7

ok, so i ran outside with a flashlight cuz this is buggin me so much.... afm is connected fine, makes sense since i didn't touch it. intake pipe looks and feels tight and snug. intake is solidly secured to the motor..... i'm so lost. What is the TID?

forced inducted fd dude

tid is a turbo inlet duct, but i think you have a n/a correct? btw do you still have your emmisions on your car?

chwkrx7

yes it is an n/a and all emissions are still hooked up

chwkrx7

well i'm going to bed, just ran codes on the car, still only have the code 9- water thermosensor- which is what i was fixing in the first place. keep postin up ideas and i'll try tomorrow after work

i would test the afm to make sure it is functioning correctly

chwkrx7

i didn't even touch the afm tho....

check where the intake pipe meets with the throttle body. make sure that's seated and clamped properly

Will it do this every time you try and start it? What will it do if you do this 5 times in a row, one after the other? Does holding down on the accel. pedal do anything?

chwkrx7

intake to tb is all good. if i try and start it 5 times in a row, it makes no difference. holding down on the accel. just makes it harder to start, and pressing the accel after it starts makes no difference. i also just pulled the afm, and checked it with an ohmeter... everything is well within specs :S

chwkrx7

i have checked all vacuum lines so many times now it's not even funny. i pulled code and the only one i have is 9 (water thermosensor- which i was fixing in the first place...)

could it be that i wired up the thermosensor backwards? and would this damage anything? i tried running the car with it unplugged, no dice... it ran before with it unplugged...

chwkrx7

i am very happy to report that we have found the problem. a long, thin piece of metal got in between the uhhh lower intake manifold i guess you would call it, and the motor. so obviously more air was gettin in there. so we tore down the whole top part of the engine again, found that, put it back together, and SHE RUNS!!! just took her for a nice long drive, it's all good. check engine light is gone too so the thermosensor is fixed

AeRx7Dallas

Sounds nice.. What is that?

chwkrx7

a stock leaky exhaust. lmao.... i need new exhaust sooo bad....
