1989 4 Runner 4x4 V6 Check engine

[samoanload]

Hi Everyone!

I just bought a awesome condition 1989 4 runner on a rebuilt engine (1000 miles on it) and it runs and sounds great.

However, i am getting a check engine light when it warms and is in drive. I ran the diagnositics myself and got these codes back:

2 & 24

Both of these point to something related to Airflow or ECU:

#2
MANIFOLD AND/OR AIRFLOW METER SENSOR SIGNAL CIRCUIT
--AIRFLOW METER/CIRCUIT
--MANIFOLD PRESSURE SENSOR/CIRCUIT
--ECU

#24

INTAKE AIR TEMPERATURE SENSOR SIGNAL--OPEN OR SHORT IN INTAKE
AIR TEMP. SIGNAL
--INTAKE AIR TEMPERATURE CIRCUIT
--INTAKE AIR TEMPERATURE SENSOR
--EC

Has anyone dealt with this before, am I looking to have to get a new ECU? And if so, does anyone know the rough cost of a replacement ECU?

Thanks!

Both of them point to the AFM.
Start by checking the connectors/wiring to it.
