how does a throttle body go bad? is that possible?

 

Maybe a little back story would help.

 

friends car wont idle for **** and he was told his tbody is the problem?

 

Doubtful. Maybe troubleshoot for idle problems instead. IACV, FITV, vacuum leaks, etc.

 

sumone told him they had same issue and they swapped tbody and it ran fine but i told him most likely there tps or map sensor was the issue not the tbody it self

 

Woulda. Coulda. Shoulda. So if he replaces the TB and it doesn't fix the issue what then? Tell your friend to stop listening to other people and diagnose the problem with solid troubleshooting instead of potentially throwing money away for uneeded parts.

 

i did i was just curious if a tbody can actually go bad if so how

 

Start the car and give it a little throttle. If it doesn't idle it's not really the throttle body.even with a clogged IACV and open throttle car should still run.
any CEL?

 

this are his words i havent seen the car yet

he said it wont idle without giving it gas when it's cold if it warms up its fine

 

I Really Don't want to say its the FITV but it could be FITV.
Someone correct me on this but "isn't FITV suppose to raise cold idles not lower?

 

Don't even know if the car has an FITV. The specs were never given.

 

doesnt have a fitv

 

What motor ?

 

97 itr

 

How about you actually go LOOK at the car and then come back and tell us what is going on with it? This is like pulling teeth as it is.

 

ok sorry guys i just mainly wanted to know if a tbody can go bad ?

 

It could Leak from gasket it could get clogged from carbon build up.
Thats all I could really think of.
