car is a 2002 rsx base 5spd with 97k
mods are vibrant race header, test pipe, and short ram intake

codes are
p0505
p0113
p0118
p1167
p1166
p1078

any help with this would help me out alot... the is my first k-seris so i dunno much about the motor, pics and help is greatly appreciated

 

do you have a defouler for your race header?

 

Yeah, I would guess that the majority of those are related to the fact that you don't have a catalytic converter.

I'd have to sort through some boxes but I still have a copy of Sport Compact Car where on a Twin Turbo 350Z they tested running a Vibrant Performance high flow cat vs a test pipe and they made considerable more wheel horsepower running a catalytic converter than not.

Today's engines are very high tech and they know what they are doing. Put your cat back on.

 

^^ test pipe vs cat

Did they tune the car when eliminating the cat... I doubt it. If you pull your catalytic converter you need kpro to turn off the rear o2 sensor and you definitely need to get it tuned.

get kpro

 

Agreed... running no cat will generate more power. Cat Converter is really there for pollution reasons not to make power.

I'll see if I can dig up a code chart to see what does codes are for you

 

p0505 Idle Control System Malfunction

p0113 Intake Air Temperature (IAT) Sensor Circuit High Voltage

p0118 Engine Coolant Temperature (ECT) Sensor Circuit High Voltage

p1167 Air Fuel Ratio (A/F) Sensor (Sensor 1) Heater System Malfunction

p1166 Air Fuel Ratio (A/F) Sensor (Sensor 1) Heater Circuit Malfunction

p1078 Intake Manifold Runner Control (IMRC) System Malfunction (High rpm)

Seems like you have a lot of sensors that are finished... I didn't have enough time to read what the solutions or what you have to do to fix it but maybe some body can help you out until I'm able to take a look... I'm at work lol
