I've installed a NOS GNX dash in my 87 GN. Since then, the car has a hesitancy to accelerate while at highway speeds. Usually at same speed 72-75 mph being worst and around 61-63 mph second.
I've tried all the obvious ignition and fuel items (new plugs/ wires, hi -flow fuel pump with hot wire,
adjustable fuel press. regulator, a few MAF sensors, and throttle position sensor).
After all this, I still come back to what occurred at time of initial installation of the GNX dash. My
GN had the digital dash originally. After the GNX gauges were installed, the Service Soon light came on each time I drove, at different times. Upon checking for codes...P024 in memory, vehicle speed sensor intermittent no signal. Disassembled dash to inspect connections which were OK. Plugged in scanner and test drove. Verified intermittent speed registry in computer.
My Service Soon light has not come on since then.
Does anyone know about this. How do I get the computer to read the speed sensor without glitching,
if this is what is the cause of my problem. Since ALL real GNX were made from GN's with the analog dash, is there a difference between digital dash and analog dashes that I am missing?
Really, really want to drive my GN on the highway again.
