Throttle position sensor?

I'd be blue too if I had a 229.....

Now I feel orange cause I got a 350 now.

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

I’m pretty sure that the Buick 3.8 (231) didn’t start coming with the computer controlled carburetor system until 1983, A pretty simple 2 barrel Rochester sounds about right for a 1980 231 c.i.

All US sold GM gas passenger cars had a computer starting '81, limited models (emission needs) had a computer in '80.

Let's try to restore some order here.

As I noted, the build sheet shows that this was a 1980 California car with California emissions which means it came from the factory with a computer. The carburetor looks correct for that, it shows the connector for the Mixture Control Solenoid and the (empty) slot for the (missing) TPS that should be there (but isn't). But -- I see NO sign of the computer wiring harness anywhere in any of those pictures of the engine and engine compartment. In other words, somebody seems to have removed the computer, or at least the harness.

It won't get through smog without the computer installed and the harness hooked up to all the gadgets (including TPS). (Unless of course you find a crook doing smog.) You can't get it registered without smog first.

That's my take, anyway. based on what I've seen.

Have to remember the OP is not in California so the smog check is likely not a show stopper. From what I've seen it looks like someone took what they ehought was the best parts of different carbs to make one.

He isn't? Where is he, then? He seemed to be saying to me that he is.

With the carb being kitbashed together with parts from God knows what, plus the likely altered wiring, the OP's car is sadly a basket case that will be hard for us to diagnose online. The car will need a good going over as there are likely more surprises in it.
