Here is the deal; idle is nice and smooth in neutral and park. When I shift into gear (including reverse) it gets as rough as a tractor. Once I start driving it is smooth.
I threw the 4runner into diagnostic mode and got codes 4, 5 and 6. Water thermo sensor, o2 and RPM respectively.
Thermo sensor checked out good (.3k ohms)
I don't know how to check the o2 sensor.
The plugs are new as of today. The wires, rotor and cap are a few days old. Timing is at 5, and 750 rpm at idle.
I need your brains
Mine hurts. I have this, and an 85 Monte Carlo SS I am working on that has just been kicking my butt.
