setup-

89 dx hatch
d16y7 motor
d16a6 dizzy with pm6 ecu
small t3
hf manifold
2.5" mandrel piping
greddy type s bov

well heres the deal...... ive had this problem before once or twice but i could just turn the car off and on again and it would take care of it.....

*NOTICE* THIS ISNT AT IDLE
the thing idles GREAT but when i push the gas in slightely the motor starts surging like someone is trying to rev the motor for me....

the thing is it ran perfectly fine up to my dads house, but after i swapped my sprint springs and fiddled with the idle (using the little skrew thing on the top of the throttle body) and just messing with the nut on the throttle cable..... im throwing all these codes....

Code 1 (1 flash) Oxygen content
Code 3 or 5 Manifold absolute pressure
Code 10 (10 flashes) Intake air temperature
Code 14 (14 flashes) Electronic air control (EACV)
Code 15 (15 flashes) Ignition output signal


now i know its going to throw the map code because im not running the missing like correct?

i bet you have your iacv/iat plugs switched. map if you dont have the missing link is your problem and o2 is a result of so many factors usually a car running like *** which yours sounds like it is

okay which sensors on the IM are the iacv/iat? and what wires from my dx harness would be going to them do you know? (i have the MPFI conversion done obviously)

iacv is the big sensors coolant runs to it and has 12mm bolts holding it on. iat is a white plug on the manifold itself held by 2 small screws
