manual choke?
Ive been having problems with the carb in the cold, probally the choke because once it warms up it runs good, it runs at about 750 rpm in idle in park and in drive about 650 but when its cold and coming to a stop it will shut off.
would putting a manual choke be better than guessing with an automatic?
What is a good idle rpm
park rpm?
drive rpm?
1986 inline 6 1bbl carb

If you still have the cat(s) in place, that tube is kinda important. The cat won't live as long without the fresh air being supplied to it. At least, that's the theory.
On the other hand, I had a cat on my truck for more than 10 years/100K miles, and the air pump never had a belt on it. The port for the air pump check valve was also plugged with a pipe plug. The cat never clogged, but it did start to rust the ends off, so I took it off a couple weeks ago, when I had a new exhaust system put under it.

Do you mean that you don't have any exhaust after the manifolds? These engines need a little back pressure to idle correctly. You don't need the cat or muffler but you should have some pipes 2.25 or 2.5 going back to at least the rear of the cab to idle below 1000 RPM.

When the auto choke in my '77 F100 300 I6 went out, I installed a universal manual choke kit. Was fun at the time.
