I just bought a str throttle body and am Installing it as we speak. I removed my old tb and put the str on and put all the hoses back where they were. My problem: When I go to start the car it cranks then shuts off. If I crank the car on and press the gas pedal it starts to run but as soon as I release gas pedal it shuts off again. No codes yet I had to adjust the throttle cable to get the pin in the throttle body. Now I just can't get it to idle and stay on.

 

When the gas is not being pressed the throttle plate should remain fully closed or should it be open a little?

 

make sure everything is on right, if nothing works then i would try to put my stock one on and see what happens
ps: what TB were u using before
make sure the TPS has the right voltage

 

Where do the throttle nuts have to be all the way on the end. The car will not even Idle

 

Sounds like your TB isnt open at all at idle. Try adjusting your idle screw so that it will at least run. Adjust down to where your idle should be once you get it started.

 

volts are correct checked them with vafc.

also check the adjustor screw, they owned my *** for awhile, damn gremlins..

 

bump still no luck I checked the screw and the voltage both are good. I start the car without the throttle body on and it ran fine.... what am I doing wrong. It just starts then stops.

 

come on guys.

 

Is the throttle plate suppossed to be completely shut when the car is idling?

 

It should look closed when it is at idle. This is a pic of mine at idle

What does your car do when you start it?

 

reset the sensor maybe

 

What do you mean reset the sensor?

 

does the STR have an idle adjusting screw? how about all the air passages used to let it idle correctly? seems like theres no air getting through at all.....

Yeah, adjust the idle adjuster screw if there is one, there should be? I believe you turn it clockwise to adjust the idle up, and counter for down! This should do it!

 

i would try to put my stock one on and see what happens
also compare them

 

I fixed it I wasn't getting an accurate reading from the map sensor. Thanks for the help guys.

 

cool, good luck
ps: i'm still looking for that IAC.LOL!!!!!!
