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 and filter.
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.
