My '98 Dodge 1500 is ailing a bit this week.
Runs smooth enough on the flats but under any sort
of load it stutters, shakes and pings badly.
It's got a new distributor cap/rotor and correct
spec plugs. I always run some injector/fuel system
cleaner through it every 3K miles when changing oil
My long time mechanics think perhaps loose timing
chain or worn distributor (the vehicle has 145K
miles on it), although I'm leaning more toward some
sort of vacum and spark advance problem.
However the mechanic told me a sticking valve might
also be the problem. He said later model 318's
(and 360's too) seem to have more than their share
of this problem. He'd been to some "mechanics
conventions" and on various mechanic's technical
groups and said others had noted this as well.
Has anyone else heard this? He did say the 318 was
over-all a great engine, but that those manufactured
in its later years of production seemed to have a
lot of valve problems.
BTW, I finally got a "check engine" light to come on
yesterday so there should be some computer help in
diagnosing the problem next week.
Any comments from AADT welcomed.
