I have the same problem; almost 20k miles on mine. But it is a recent change in behavior. In December Houston helped me adjust my mixture to pass the smog test. It was failing very badly, but mileage did not improve as greatly as I expected from the huge differences in the readings. I do know that I need to get the exhaust gaskets done, but am fearful to tackle this project myself after listening to the talk about broken studs. Could exhaust-manifold leaks effect cold running and mileage? ----- Original Message ----- From: "Joe Palatinus" <jpalatinus@xxxx> To: <dmcnews@xxxxxxxxxxxxxxx> Sent: Saturday, October 28, 2000 9:14 PM Subject: [DML] Re: Cold engine and smoke and gas problem, continued > I have been trying to solve my 15 miles to the gallon problem for quite > some time.
