Default error code p0110 (intake air temp sensor) thoughts?

Hey guys, I just recently started throwing code p0110 as long with severe misfires:

past info, I did blow a hose and overheat a few days ago, but upon replacing of hose/radiator/flushing cooling system, the car has been running great.

the car idles PERFECTLY until any throttle or rpm fluctuation... IE there are no misfires until i place my foot on the gas, put the car in drive, or turn on the A/C.


troubleshooting completed:
-The car idles with maf disconnected.
- i have swapped to a known working maf, the issue still occurs.
- i have spot checked fuel lines from inside the tank/ fuel pump to undercarriage ( should i be looking closer here?)

strange issue that makes me think its fuel related


- the car runs MUCH BETTER ...to the point where you have to listen closely for misfires, if i leave the fuel pump ecu disconnected (located behind rear q/r cover) ...BUT if i idle and use the AC, it has a severe misfire,

--- id like to check the continuity of the wiring from the maf to the IACV but i am waiting on a working multimeter, mine are throwing out crazy numbers at the moment (187 instead of 0 or 0L at default readings)

my thoughts are this is definitely fuel related, but i could clean the IACV, bypass the fuel pump ECU entirely (through wiring), or swap the ECU. I am just not looking to make any permanent changes or throw money at it without appropriate testing or valid reasoning.


thoughts?

p0110 is an IAT Circuit Malfunction and a google search came up with this

this is an awesome site by the way, tells you absolutely every single code in a generic way so you can start googling away

thanks for the update.


so the issue only occurs during closed loop (only occurs when the car is warm OR not wide open throttle)


its not the maf
not the coolant temp sensor
still occurs with both o2 sensors unplugged
tps shows appropriate resistance
grounds are secure


what else should i be checking?

edit. it was coolant in the sparkplug valley. new plugwires / boots, removing coolant and issue was resolved.
