Hello everyone I am trying to get a straight answer regarding throttle position sensor. I'm looking to buy a 1980 Buick Regal 3.8 v6 231 with a dual jet carburetor. So was I'm looking over the engine I notice there is no throttle position sensor plugged into the carb on the front right there's a gap. And I have one on my 82 Regal same engine same carb.he told me my carburetors set up to where it does not require one the car does idle rough and I was just wondering is there such a thing as a vehicle not requiring a TPS sensor? And the answer would be greatly appreciate it before I buy this thing. Thanks a lot
