If my TPS sensor was bad would it not allow air into the intake manifold? I notice there is a passage in my TB that goes to the TPS sensor but dont know what is inside of it.

 

I think you are referring to the IACV, the idle air control valve.

Which engine do you have?

 

d16y8. my car only stays on if I hold onto gas pedal, so at idle it dies, so i figured the tps isnt letting air in

 

The TPS just measures how much you are stepping on the throttle pedal. The throttle cable is what moves the throttle plate, not the TPS.

That's smells like a IACV issue.

 

My car was working good and then I removed my IM and cleaned it up, just unplugged the hoses and electrical connector to the IACV and now it's giving me these problems, I dont know what could have happened. I'll clean it and then if nothing guess I'll buy a new one.

If I unplug the IACV electrical connector on normal circumstances the car would stall at idle correct?

 

Maybe it's a vacuum leak? Double check your work and make sure you didn't switch something around or break anything by accident.

 

already checked for leaks, on the flipside the only way it idles without dieing is if i remove this cap. Bringing me to think it has to be the IACV now since it is not getting air at idle. These two have always been capped btw and worked fine before.

 

Is there a CEL? If so, what is the code(s)?

 

I took the iacv off and cleaned it, there was not any coolant in it or the hoses yet because i Havent let it bleed all of the air out yet... Would no coolant to the iacv cause it to not let air into the IM?

my car currently is open headers inside of a small garage and if I let it idle for a while the neighbors will call the police...
