shuttering between 3000 and 4000 rpm

when accelerating moderately hard in second third and forth there is lots of shaking at about 3500 rpm but does not happen when floored or accelerating slowly

Check spark plugs and wires. If they are old they need replacing.

check your motor mounts.

I have the same issue. I think ill look into my spark plugs and wires. I dont think it could be the motor mounts.

shaking is different from stuttering. stuttering would be a air fuel or spark problem. shaking is most likely a mount. guys youd be surprised i had the same problem I had 2 torn motor mounts.

i don't know if it really had anything to do with it but i took off the egr and cleaned it up and it made it alot better its still time for new plugs and wires to and its a shuttering not so much a shaking but thanks for the info guys
