I was gonna take mine into the shop, but the guy there said I need to get the O2 sensor to where it is reading from all cylinders. Right now the stock exhaust manifolds are being using and the O2 sensor is plugged into the front one. So I dont have the reading of the back 3 exhausts ports.
So need to do that then I can take it to them to see what's up.1990 325is

Vacuum test completed yesterday, everything seemed correct which would indicate no exhaust restriction, and i believe no vacuum leaks.
car has its good days and bad days.
when I drive with the maf unplugged, does it go into the same open-loop as if I unplugged my o2 sensor?Current:

i know everyone is sick of seeing this thread popping up....but just throw random shit out there. ill try it at this point. im getting close to bringing it to a shop lol.
Things i havent tried but plan on trying as soon as weather cooperates :
disconnecting o2
replacing vanos seals (i know this would give bad mpg, but cutting mpg in half? seems excessive)
new engine harness (might go obd2 at that point)Current:

So back during winter when it was cold and minnesota was using their less efficient winter gas, I was going about 120 miles max off 9 gallons of gas. (13.3 mpg)
Now that summer gas is back, I am back up to 180 miles on 8.5 gallons of gas. (21.1 mpg)
I'm still having power issues down low, so I plan to do vanos seals next. But I find it odd how just having warmer weather and better gas improved my mpg by that much.Current:
