1998 maristar 200 lt1 engine- tach reads 4400 at 30 mph and pegs out at wot.
manual indicates 4800 - 5200 at wot is normal
engine used to idle at 900-1000 rpm and now around 1200-1300 at idle
oil pressure and temp within range- engine sounds and runs good.
should i ignore tach readings or replace- dealer says all connections are good.
