Idle suddenly drops when fully hot 62 4GC

62 cadillac with 4GC, 60,000 miles.Runs good when warming up, I can even drop the choke open off the fast idle cam and it continues to run fine.  That means it's off the cam, off the choke completely, everything seems good.  Then, and this happens very suddenly, after about 25 minutes of running when it's fully warmed up (just over the quarter mark), the bottom just falls out from under the idle and it drops to near stall speed.  If I put it in gear, it will either stall or barely run with a…See More

Here it is:

 

The main factor is the length of the ceramic insulator from the middle of the spark plug to the tip (where the spark happens)

Lower Front End Ball Joints

Posted by Logan Robb on May 11, 2023 at 9:04am 7 Comments

Good Morning all! 



I took the 64 into the shop to have some adjustments completed and in the process decided to have the lower ball joints replaced as was recommended the last time I had it in. I ordered the parts and came into the shop. They quoted me nearly $500 to replace those lower ball joints requiring nearly 4hrs of labor. Now this is a reputable shop and they know me by name here and they will continue to get my business. I am just questioning what on earth is…
