i put an ex cluster in my 93 civic dx coupe so i could have a tak. the speedo in this one says im going five miles an hour over compared to the last one. I no this because i used to do 30 in 4th gear and now i cant until 35mph. same with 5th gear, car lugs unless im doin 45mph and it used to be 40.


another problem is my idle will drop to 400 or so, but car wont die or sputter. I thought this was happening befor, but without a tak i coul never tell. any advise on why any of this is happening and how to fix it would be apreciated. new plugs and wires along with valve adjustment was done 5-6 months ago
