So my discovery won't idle correctly (Floats between 750-1100 rpm, abruptly doing so)
And has a pretty rough misfire.
But heres the weird part, it will accelerate and rev just fine up to 5500 rpm and have plenty of power, but after I let off, it starts to miss badly and sometimes stalls.
I have checked the idle air control valve, stepper motor, throttle position sensor, all fuses, and has new plugs and wires.
Any clue you guys? Im checking fuel pressure today.
