300zx 92 NA yo-yo idle 1500-2000 RPM MAF?
I have 92 NA That yo-yos back and forth between 1500 and 2000 rpm cold or warm engine does not change the condition. Car runs fine otherwise, idles good and runs fine above and below this RPM range. Things that I have done already to the car.
Replaced 3 dead injectors others ohm out fine
Replaced all spark plugs with recommended
Proper plugs
Proper plugs
Replaced fuel regulator and filter
New TPS set correctly
Checked and fixed air leaks
New Air Filters
Replaced Knock Sensor and Harness (Relocated)
I have no codes flashing now other than 55
I'm down to either MAF is Bad (have cleaned it already) or Idle control needs cleaned but would that effect anything under acceleration?
Around here in traffic most of the time your sitting in this RPM range surging up and down unless you shut overdrive off then RPMS stay above this range most of the time (car is automatic).
Any help would be appreciated I have look around and have not found any post about this condition.
