SI CEL... runnin rich?

infiniti_4_life · 10-09-2007, 04:06 PM

Hey everybody, So today i was cruising on the highway 95 ish,

and out of no where I get a CEL. I drive over to autozone to have them read the code. The thing said Bank 1 running rich...? I think it means cylinder 1 but could be the manifold runner #1... I dont know.

I've had an Injen CAI along with IMG and Throttle body Gaskets for about 6 months now with no problems. Just wondering what could be causing it to run rich all the sudden. I'm just glad its nothing major... Any thoughts?

Bank one is the only O2 sensor you have on a 4cyl engine (before the cat). If you had a V6 or V8 engine with two exhaust mainfolds there would be two O2 sensors before the cat and this would tell you which one was reading rich (bank 1 or bank 2).

A rich condition could be cause by a lot of things. The problem could be ralated to your intake. If the airflow around the MAF is different it could cause a slighly rich condition. I assume you mean 95MPH ish? If you were running at this speed for very long this could also contribute (higher speed requires more throttle which=slightly richer condition). Just a possibility.
