Alright so ive been procrastinating a tad (just got a new job).
and Im 5 codes away from passing emissions.
I have a 1997 2wd Ranger 2.3L 5 speed
They are
O2 heater malfunction (1&2)
excessive egr flow
bank 1 lean
code 1443, i think thats something with the carbon canister.

This is AFTER replacing both o2 sensors, new plugs & wires, IAC valve, egr sensor, timing belt & tensioner.

Heres what ive checked:
Fuel pressure is 30-32 @ idle, 38-40 with engine off (pump primed)
timing is at 8* base
Intake air temp sensor & coolant temp are reading correctly based on the scanner info.

When i checked the timing I also double checked the secondary coil pack, and come to find out cylinders 2&3 arent sparking.

Ive searched on google and people point to the ICM as the issue but I cant seem to find it anywhere in my engine bay.
