87 pontiac 6000 2.5l 4
Today the weather was great, 19C and when my car started the damn choke was on, it remained on for quite some time too. How do I fix this, do you suppose is a sensor problem like MAF or O2?

I thought carbs and chokes were gone to fuel injection in those cars by 1987? None the less the last ones were a pest and the chokes were shut off by electric heating so see it that wire has power and a good connection. The last ones were rivoted in (round black plastic) where they get the spring action and shut down from. They used to require drilling out and came with fasteners to replace as I recall. You can feel the thing warm up with just the key in "run" position and choke should open wide from a cold engine.
You said 19C which suggests you are not in the US and they may have made an export version of that car which I didn't think GM did much more than make a metric instrument panel. T

You are probably right about my car not having a choke, I assumed it did only because of how it ran in the winter. The question then becomes, If I do not have a choke, what would cause my engine to rev so high when the engine is warm?
I don't know too much about cars, but to me it feels like the MAF or O2 sensors are out. The car is getting more gas then it is burning. if you stand behind my car you can smell raw gas. Also, if you run my car for a while, shut it off and open up the carburator, there is raw gas in there too.
Any Ideas?

Do you have any "check engine" light on?" The car is sensing temps and may just be fooled thinking it's cold all the time or the idle motor system has srewed up but if you are smelling gas out the exhaust I would guess that it's a cold sensor or wire or problem with engine control computer/module and could be tricky to figure out. The overload of fuel will hurt cat converter(s) so we need to find this quick, T

No lights are on nor have they ever been on since I've got the vehicle.

Places like Auto Zone will run a scan for you for free - of course hoping you will buy parts but that needs to be ruled out if nothing else right now. T

There a so many possible reasons for this car to be doing this that the list is almost endless. I would take it in and have it diagnosed; you don’t have to ok the repairs just because it’s in someone shop. Yes you’ll have to pay for the diagnosis but I’ll bet you it’ll be less expensive then throwing parts at the car or like what carjuncky said burning something else out while you’re screwing around with the thing.
If you’re unsure of their diagnosis post back here and we maybe able to confirm their findings or raise a few questions for them to back up the reasoning behind their diagnosis.
