I have a 1997 Dodge Ram 1500. The truck is in great condition, with very low mileage. I have recently started having a problem where the truck will stall when I take my foot off the gas pedal.
I have run a diagnostic code check with my ODBII reader and have gotten
no codes. Vacuum is good, changed spark plugs and there are no signs of
sludge, burnt oil, bad fuel/air mixture, or bad fuel. This generally happens
when the engine gets warmed up, I can't seem to force it to happen when it
is cold. The truck will drive just fine, but when I let off the gas the RPMs go
down to near 0 and will either recover or not. When it does not I lose my
engine and everything along with it. I can usually just slip it into neutral,
restart it, and drop into drive without any problems. What could this be?
