Dies when idle in gear

Dies when idle in gear
I can idle in park and it won't die, stays around 1000-1500rpms
But as soon as I put it in drive it will slowly drop unless I keep fuel running to carb
I had read to clean the idle air control but I can't find it.
Anyone with carb engine know where IAC is, or have any clues to why I would die in idle?

Re: Dies when idle in gear
So I can drive it fine but when I stop at a redlight, rpms will slowly go down and it will stall. But if I just sit in park it will just have a rough idle.
What I mean by keeping fuel running to carb, If I stop at a light, i have to hold the brake and the gas pedal to not let it stall.

not sure what that is where the mc solenoid goes.

Re: Dies when idle in gear
You have a major rectum-reaming malfunction going on there. Your problems go WWWWWAAAAAAAAYYYYYYYY deeper than mere failure to idle.
It has no IAC. That's a EFI thing.
You have the computer-controlled carb up on there but not A SINGLE TRACE of the computer wiring to control it. Can't tell whether the dist has vac adv or not but if it doesn't you're more or less QUADRUPLE phuqt.
Looks like somebody spent a little too much money on Edelbroke and "krome" and not enough on common sense.
Let me guess... the Edlebroke Triangle Of Death air ... obstruction, too?
A little history might help point you in the right direction. Also, a few more details, like make, year, & model. Although I can guess it's probably 84 or older.

Re: Dies when idle in gear
Right: you have the computer-controlled carb, but no computer controlling it. It originally came with a computer-controlled distributor as well, but it may or may not still be that with no control, or maybe if you're less unlucky, one with complete mechanical control, like in days of old.
The whole carb situation is a recipe for very bad gas mileage and all manner of driveability issues. I'm surprised that your only complaint is poor idle. If the dist is still the original then the problems are compounded.
Basically, someone who either didn't know what they were doing or who didn't care about the outcome, has worked their magic on it. You have a steaming pile of problems to sort out before it'll ever work right.
As Tuned said, put up a pic of the dist that shows the pass side, which will show whether it's the computer-controlled one or not. Also get a pic of the area around where the pass side fender meets the AC housing, showing what, if any, of the computer wiring is still there.
I'm afraid the car may have already been "improved" too much to be able to be properly repaired. But even so, it might be possible to salvage it, by totally de-modernizing it and returning it to the 1950s. It won't be cheeeeep or eeeeezy, either way.

Re: Dies when idle in gear
That's not a ccc-qjet. Note the rear 'dash-pot' and lack of TPS. Looks like the q-jet with the fuel enrichment solenoid.
if it's original to the car it may be an export model.
perhaps the situation is not as dire as prognosticated.

Re: Dies when idle in gear
So I am missing an electrical connection to the passenger side of my carb? I had noticed a loose wire when I was under the hood Saturday. I have a few random electrical connections that just don't go anywhere.

Re: Dies when idle in gear
You could be right. I don't see the TPS connector although there are some other ambiguous things.
There IS a 2-wire coolant temp sensor there though; only reason for that would be a computer-control system of some sort.
So yeah: an electronic enigma, wrapped in a conundrum, and delivered on the horns of a dilemma.

Re: Dies when idle in gear
i vote not original to the motor.
I don't think the rear dashpot was used on these motors even for export?
A temp sender is installed in the water neck but I don't see the ECM harness the pigtail should come out of.

Re: Dies when idle in gear
You are running this engine with that hole in the heater hose???
Is there any coolant left in the cooling system?
