finished swapping in a 99 b16a2 into my 95 si hatch with a chipped p28 i had on my b20vtec years ago. everything went well and started right up fine. i had the check engine light on and just thought it was the o2 sensor that i didnt hook up cause the on the stock eg harness is not long enough to meet the o2 plug on the dc header. Then the idle was jumping up and down so i thought maybe the tps sensor or some air in the coolant. swaps only been in for about 4 days and i finally got around to checking the CEL codes and im getting 7-tps sensor, 10-IAT sensor intake air temp, 41-primary oxygen sensor.
It drives fine for the most part just got to unplug the tps sensor till it idles fine then the car is great. i have noticed also that i filled up on monday and only got on it three maybe four times and im at 113 miles with just under half tank! gas mileage is shitty! im thinking fuel filter, spark plugs, and doing a proper timing on it would help me out. anything else to avoid this gas guzzling hatch thirst quenching problem?




on the header do i have to extent the wires in order for them to plug up together? or buy a aftermarket o2 sensor with longer wires?

can i just recalibrate the tps sensor if its off or will i need to end up replacing it?

i see the spot where the IAT sensor would have been on the manifold but these b16a2's had them in the intake arm. ive read people drill/tapping the manilfold and fitting one on but i can find any how to or a good write up on how. if you know of one detailed please let me know.

 

What are the colors for the wires going into your TPS and MAP? Is it possible you mixed them up? For the IAT you can just drill a hole in your intake arm if its metal and put it in there like this:



For the O2 you can just use an extension harness. check my sig below

 

thanks for the pic!!
when i extend the wires for the IAT sensor and mount it on the intake arm i read somewhere that its got to be about 6 inches away from the thottle body, is that correct?
ill be buying that o2 sensor harness for sure.
the map sensor has three wires of course, one a solid white wire from what i can tell.. the tps sensor does not have a solid white wire, its white and something else. i have them correct cause when i switched them last light to just make sure it was correct the car BARELY wanted to idle.
