Evening guys, so I was working on the car this evening and had been reading some threads about running rich issues. My ride has always smelled rich no matter what, even when the motor was stock it smelled like it was running rich. Last year about this time is when I rebuilt the bottom end, added trick flow track heat heads, cam and intake combo, msd distributor, 190lph fuel pump, 75mm throttle body, and egr spacer. I have since purchased 30# ford racing injectors, they came with a "matching" c&l mass air flow meter. Now I tried to install the injectors and the car ran like crap, which leads me to what I found tonight, and shouldn't have overlooked this whole time. Oxygen sensors. I warmed the car up and checked voltage on my signal wire, both sides were hovering around 200 to 250 millivolts. Not even close to performing properly. So I just want to be sure, and double check with all the great minds here on the forum, my sensors are telling the ecm that I'm running lean, correct? Well my nose and everyone else's nose in the shop, say I'm running very rich. So if the sensors send garbage into the ecm, I must be getting garbage out, right? I have no clue as to when these sensors were installed, they aren't factory, but they do look like they have so mileage on them. I'd appreciate some insight to know if I'm on the right track, I might pick up some new sensors and replace them to see if there is any change. Thanks again in advance.
