How to fix throttle body leak under TPS?

[GNRick]

I have a HUGE vacuum leak which I found with my home made leak detector. I removed the TPS sensor to see it better. Do I have to remove the throttle body to repair it? Ok, I just found this thread, GBodyparts carries the O rings. Can this be repaired on the car? Thanks.

You should be able to pick up those throttle shaft seals from Gbody and others and replace them yourself. I don't see why you couldn't replace them while on the car. Its really not a big deal. Hopefully someone else will chime in as well.

Get the seals and do it. It can be done on the car. Easier on the bench but that's your call.

Throttle body seals

Its a lot easier with the throttle body off the motor and maybe less of a chance of damaging new seals when driving them in.
