[DML] Re: Stalls after starting

["David Teitelbaum" <jtrealty@xxxx>]

15 MPG is awful mileage. No wonder the car smells "gassy". First off
look for fuel leaks, that can kill your gas mileage. Next go over
every vacuum hose. Make sure they are all soft, not kinked, connected
right and don't leak. If the car hasn't been tuned-up that is next.
Have the fuel injectors cleaned and replace the injector seals. Your
fiddling with the mixture screw is a hopeless attempt to richen the
fuel mixture to make up for the vacuum leaks. Dragging brakes can also
kill mileage. If the fluid is dark and thick flush the brakes, you
might have a sticking caliper which means rebuilding the brake system.
Alignment affects mileage. Look at the tires and see how they are
wearing. Finally for your hard hot start pull the short rubber hose
off the back of the accumulater and attach a hose from the accumulater
into a pail. Turn the key on and see if fuel comes out of the
accumulater. If it does then order a new one. A bad accumulater
doesn't affect performance or mileage, only hot starting. Vacuum
builds up almost immediatly once the leak is stopped. Vacuum is Power!
So if you don't have vacuum you don't have power. Vacuum is how the
engine gets the combustible mixture inside, the higher the vacuum the
more fuel, the more power. This only applies to naturally aspirated
engines like a stock Delorean.
