I have an 87 Pathfinder VG30i with 195k miles and a 5 speed.
She seems to be all stock with no redneck tech except for an instrument panel is from a different model Pathfinder (maybe an SE or a S, it is missing the second fuel gauge, and the interlock button makes the fuel light on the dash come on)) and where some one stole the aftermarket stereo out of it.
First problem:
Idle...the idle fluctuates between 1800 and 1200 RPM. The Idle stop is backed all the way out and the RPM speed will never fall below 1200.
Second Problem:
Accelerating or Revving the engine above 3200 (or so) RPM causes the voltage to dip (Blower fan slows and dash dims). when the Engine speed drops to 2000 RPM or below the voltage returns to normal.
Third Problem:
I feel the thermostat is bad..Dosen't produce much heat from the heater.
I was going to pull the engine codes but it is so dang cold in Denver lately.
But the Pathfinder is Kicking A$$ in the snow.
