Okay. So I did a quick search for fuel mileage and I found that most people easily get better... Actually a lot better gas mileage than me. I'm running about 9:1 compression on a rebuilt 7M-GTE, can't find any boost leaks, timing is dead on at 10*, pretty sure my TPS is set correctly. Don't know what else to check. Getting a Max of 16 mpg. And that's highway. Around town I'll get closer to 13-14 mpg. Anyone have any ideas?

Is the engine is fuel control? Either there's a typo or I'm not following at all

I'm asking if it's operating in closed loop. Is the O2 sensor cross counting the specified amount within the time specified in the TSRM? Is the average voltage about 450 mv? In lieu of that is the emulated O2 signal on Vf cross counting with an average of 2.5 volts?

Can't tell? Don't have the stuff to measure it? So much for those say narrowband displays are useless...

I'll crack open the TSRM and check it tomorrow. I have a feeling the o2 sensor has kicked the bucket.. but my feelings are usually wrong haha

Sorry. Its completely bone stock except for a MHG raising the compression ratio
