I have terrible gas mileage on my mini-me, running a p28..this set-up is draining my gastank like its draining my wallet. I have a 1-wire o2 and I know the p28 is 4-wire is this the reason why? Also I got desprate and found a po5,p75, and I tried to hook them up but the it started to smoke from the ecu/ecu plugs what the hell caused this..but it seems it didnt do any damage..anyone can explain this to me and try to help my gas mileage improve with any suggestions, I'm all ears...

 

Do you have any CELs?

Convert to a 4 wire o2.

 

Did you swap the p28 and do the mini-me at the same time?

 

Its definetely the o2 sensor, also check maybe if you got a map sensor code b/c when i did it, it was terrible with gas also.

 

Get the car tuned. You may be running overly rich in fuel -

 

Oh its running rich, I can smell it, at idle, red lights, and when I park in the garage. I do have some CEL's but I havent check them.I did the mini-me and swap to the p28 right away.

Maybe you should...

 

i would defently check the cel's ASAP. and as for the smoke coming from the the ecu/plugs that is kinda scary.

 

I'm getting codes 10 and 41..
10 is (IAT) Intake Air Temp.
41 is Primary oxygen sensor heater

..I had no codes before the mini-me swap, so I think code 41 is because its a 1wire o2 compared to the 4wire o2 the p28 is looking for..where is the IAT anyone have a picture?

 

Its a white sensor on top of the intake manifold, usually located on the 1st or 2nd runner.

 

is ur oxygen sensor..same thing happened to me...it does smell rich and ****...so jump on that and u would be ok

 

I have a jdm d15b head/manifold so some sensors like the Purge Valve Control are not on this manifold..there is a white sensor though so its must be it, have to screws..is the plug also white in thats hooks up 2 it?
