EricM9104 Posted November 4, 2012 Report Share Posted November 4, 2012 If you don't know...Take it to a shop. Well I honestly don't trust any shops around here. The only shops we have are car lots and a few mechanics. No one that works with FI though. That's why I figured I would ask, as there are more experts on forums than there are locally. Do you have proper funding to fix it right? Firsthand experience with said shops? 2015 Honda Civic LX 4dr | 24k miles Stock H/U and mids/highs Power Acoustik GW3-12" D2 Sub HiFonics BXX1200.1D @ 1ohm Random 2.5^3' dual ported box NVX LOC Stinger wiring throughout 1977 Chevy SWB Cammed 350 Dual exhaust Cheap Wish stereo Link to comment Share on other sites More sharing options...
94jettameowpsst Posted November 4, 2012 Report Share Posted November 4, 2012 What's it tuned with? O2 sensor sounds bad. What did it idle at when you bought it? It should either sit at 14-15 or cycle from 13-15ish at idle. 8:1 is borderline not even drivable and you'd have gas coming out the exhaust. Check your plugs and post a pic or tell the color. Cold will make it run lean, not the opposite. 150.1 @ 38hz142.3 @ 20hz (windows down)Only 2 batteries Link to comment Share on other sites More sharing options...

Cold will make it run lean, not the opposite. I'm assuming it's the o2 sensor. The car runs fine and it sits around 14.5 at idle. I will check the plugs. But I've been reading online and it seems like the o2 sensor is the problem. The thing is, with the greddy system I have, it's not a true wideband. It has a dedicated sensor but I guess it's considered narrowband. Even though it doesn't hook up to the car's stock o2 sensor. The greddy sensor is only $110 so I will just pick one up and see if that fixes the problem.

Also typically if your o2 sensor goes bad it will not idle at 14.anything. It'll lean out and be like 15-17 bc the computer sees it as a rich condition and tries to pull fuel.

Ya I guess I really just need to switch to a wideband. But all of my gauges match and I really wanted to keep the Greddy gauge. Oh well I guess. But my ECU is the Greddy e-manage ultimate.

94jettameowpsst Posted November 5, 2012 Report Share Posted November 5, 2012 Aem has a setting to ignore the factory o2 sensor and base all readings off of a wideband. If you don't wire it to the ecu it just means you can't log the information bc it doesn't have a voltage output being measured by whatever piggyback unit you log with, wont effect how the car runs or reading one bit if its not wired to the ecu. 150.1 @ 38hz142.3 @ 20hz (windows down)Only 2 batteries Link to comment Share on other sites More sharing options...
