Quick question here, I have a 90 Olds Delta 88 and last week I found that there was a bad oil leak at the front left corner where manifold mets the block. I pulled the manifold and replaced the intake manifold gasket and reassembled everything. All went back together just fine but when I started it back up it was idling rough. Hooked up the scanner, SnapOn MT2500, and it showed code 22 TPS low voltage?. Is the TPS going bad a common problem or did I somehow mess it up? The car was running fine before I did the work, but over the last few months the mileage has been getting worse.

Thanks

This link will take you to a write up that explains how to test the TPS:

I cant remember the exact value right now but by scanner was giving a live reading at idle and it also told the acceptable range, and mine was WAY off of acceptable. I will do this test tonight and most likely make a trip to the parts store tomorrow.

Thx
