[DeTomaso] MY NEW 74 PANTERA

[Doug Braun]

Ian,

Start by having someone keep the car running by high idling it from the cockpit or tighten the carburetor's idle screw to raise the idle.
Then, one by one, remove any vacuum hose connections to the intake manifold and plug the manifold's open fitting with your finder to see if it smooths the idle.  This includes hoses going to the distributor, a vacuum controlled water valve, and the larger brake booster hose and the rear center of the intake.  Since the brake booster hose goes all the way to the front trunk via an interim pipe underneath the car, it is especially suspect as the culprit in such rough-idle situations.

That makes me feel good! I just bought my 1st 74 Pantera, paid 136,000 plus $1500 to have it shipped to me in Texas. Previous owner claims it has 7500 original miles and now that I have it and checked it out, I believe it? However, he also claims that it was sitting for 10 years, and I believe that too. Won't idle? feels like it has a vacuum leak, took for a drive ran pretty well but every time a came to a stop it would start to die (lot of heel and toeing). Took it easy as it has the original Arriva Goodyears 48 years old on it, ran cool for a while then got up to 230 before I got it back to the house, guess it par for the course 48-year-old super car.    Everything is original! where would you start manifold gaskets, carb, drain the coolant ?
