1989
Miss at idle

Code 2-3-1 compensate for rich or lean at cruise

Check engine light on

Since this has started...

New

Plugs
Cap
Rotor
Wires
known good AMM
O2 sensor
Cleaned Idle Air Controller
Cleaned Throttle Body
New Thermostat
New Belts
New Timing Belt
New Motor and Transmission Mounts

Some of my work has no relation to the problem, I just have time this time of year to work on it.

I have not checked the Coolant Temp Sensor

Cold temps this week have made it worse.

    If you haven't already, clear the codes by removing fuse 6 and see if they return.
    Take the vacuum hose off the fuel pressure regulator and smell for gas or fuel coming out with the engine running.
