BlueZ31 Posted August 28, 2010 Share Posted August 28, 2010 Recently started having tachometer issues, the needle wont go past 2,200 rpms even at full throttle acceleration and at cruising speeds the rpms are about 2-300 below where they should be (1,200rpms in 5th gear at 55mph on a stock 87 N/A is not right) i changed out my coil which temporarily solved the problem but a week later the issues come back to haunt me, along with a very loud humming noise from the drivers side dash area present only while the engines running. Anyone had similar issues or know of a fix? Quote Link to comment Share on other sites More sharing options...
