That does not sound right to me, nor match the response of narrowband gauges I have seen in use. At cruise/idle the narrow band sensor should be going back and forth between rich and lean. Narrow band sensors switch between 0 and 1v output when the a/f ratio goes from below 14.7:1 to above 14.7:1. At cruise and idle a properly functioning EFI system will constantly be oscillating from 0 to 1 v of output from the narrowband o2 sensor, therefore at cruise and idle your gauge should be giving you the light show. At Full throttle it should be on the green lights, as your narrowband o2 sensor should not have any voltage switching as the afr SHOULD be much lower than 14.7:1. With that said I think your narrowband gauge or sensor is not functioning right (if you have no codes for the sensor my money is on the gauge). Also as Hvyman said you should just get a wideband if you want to know what is really going on in terms of AFR. That way you will know the exact afr the car is at.
OK i don't know whats up with mine then its ether yellow or green at full throttle and red while slowing down. no crazy sweeping or flashing lights just 1-2 bars light all the time.
Also its amazing what i can look at and not actually see, one of the vacuum lines was not attacked to the blue vacuum thing so maybe that will change something i haven't drivin it since i fixed it.
about the boost gauge plumbing its defiantly in the nipple above the egr rig. i hope you know what i mean by that.
Does any one know were i can figure out how to properly set a greddy profec ebc? iv searched and search but all the ones i find have more knobs and buttons than mine.
