Running Rough at about 1700 rpm
Got my transmission fixed and all is well with that. However, I now have an engine vibration at about 1700 rpm. The motor mounts have been checked and one replaced when the tranny was rebuilt. If you rev the engine, in park or neutral, to 1700 rpm, you can feel the vibration. Soon, I plan to change the plugs and wires and see how the plugs are firing (checking for any deposits, etc.). Is there any other items that I should check to eliminate this sputtering? This sputtering is not severe enough to turn on the Service Engine Soon Light. I have had the car scanned and there are no codes set in the computer. Any thoughts on types of plugs and wire replacement parts? Any input would be appreciated. Thanks!
