TPS in Q-jet is broken

[WIKD CUT]

Found out that the TPS in my 87 cutlass is broken. I think that this may be causing the rough idle. Anyone else think that this could be the problem? Can anybody tell me where I can find a replacement? Thanks.

Any parts store should have or be able to get a replacement.

I had this issue with my 84 H/O. Change out the TPS and runs great
