stumble or jerking at 55

[dniksch]

I get up to 55 or plus and let off and the truck stumbles or jerks after I take foot off the gas. Any ideas?

When was the last time you checked on your camshaft syncro? They are known to cause jerks or bucking at higher RPM's. They will not through a CEL either.

I had the same prob if i held it steady throttle. I think i was getting a clogged injector. Try some Seafoam. That did the trick for me

ok, I will. I do all the plugs and wires and cap/rotor. and helped out a lil at the lower speed. thanks for all the help everyone
