P0113 Iat sensor 1 circuit high input
p1259 air and fuel metering
P0135 heater bak 1 sensor 1 I just replaced this yesterday dont know how this happened?
P1337 manufacture controlled ingition system misfire.

Does anyone know know what these codes could be able . my car idles real rough and seems like the car is misfiring . The dizzy has been replaced,cap and rotor, plugs and wires.

Any help would be appreicated.

 

What. Car?

 

^this

...and reset the ECU to see whether any of the codes return.

 

It's a 97 hatch with a d15b bottom end n z6 head . Tried resetting the light numerous times nothing . Car idles like crap it stays at a constant idle rpm. But the car pops through the exhaust like its missing ? Any suggestion I've replaced the dizzy cap and rotor plugs and wires . Iat sensor is missing and not plugged in . Could that make the car run like absolute crap?

 

What ECU?

 

Jumper harness to a virgin p28 ecu . I put back in my p2p ecu same thing

 

I just saw this after re-reading it.
C'mon man. One of the codes is FOR the IAT sensor. What do you think? If you know there are deficiencies you need to fix them.

Installing a working IAT sensor would probably fix at least TWO of your issues.
