Hey fellas...

88 civic dx
motor from 94 dx (d15b7)
-just motor
-88 intake manifold
-94 dx exhuast manifold
-swapped just the block and exhuast manifold, then put the 88 stuff back on


My check engine light is coming on at half temperature.
The car seems to be running fine, I just dont want it to be eating gas like a savage.


The o2 sensor just got done today.. the one right near the dip stick.
Is there a second o2 sensor for 88 dx's? Or is there a plug on the old manifold? I didnt see one when installing it.


Also, I will be checking the ecu for any codes it is throwing as soon as I can get the cover piece on.

Do you guys know a good way to go about the bolts that hold the cover on for the ecu are rusted and I dont think 'normal' tools are going to work here...

 

the stock '88 dx has only one 02 sensor....
