'86 CCC Quadrajet High Dwell
Cliff Ruggles:
That is what I suspected, and that is what the problem is.
I haven't seen a single good working sample from any of the commercial sources in decades, and the CCC carbs are usually the worst.
The really bad news is that it is difficult if not near impossible for use to help with those, as it could (and probably does) have a multitude of issues and problems related to assembly, low quality internals, and lack of attention to detail.......Cliff
PS: did you keep the original "damaged" unit, and what was damaged on it?

The original unit was sent to them as a core exchange, it had a massive air leak from a big U shaped dent in the side wall where the airhorn meets the bottom casting.
What can I do to fix the problem?

There's someone parting out an '87 Caddy like mine, same engine. Do you think it would be a good idea to ask him if he'll sell me the carb?? **ALSO I forgot to mention that sometimes the check engine light comes on for the o2 sensor when I'm driving at around 60-80Km/h(35-50mph) for more than a few seconds, when I speed up to highway speed it'll go away.... It's code 13 which I thought was pretty odd
Cliff Ruggles:
The best repair will be to obtain an original unmolested core and completely/correctly rebuild it, so good idea to get that one if you can......Cliff
