ive got whats been said to be the hardest cel to diagnose.

got a 93 SI with a b16a2 swap

i installed a new aftermarket 02 sensor with the swap and had to extend the wires due to my aftermarket manifold.

fuel filter was changed about 4000 miles ago.

and no knock sensor is wired up (not getting the cel tho!?)

car runs rich and occasionally has fluctuating idle. but when moving it has no signs of any problems except the cel

i missing my main ground wire from my tranny housing so that getting replaced in a couple of days, doubt thats causing it tho.

its worth mentioning that this only comes on after 10mins or so of driving at 60mph+

please can you guys give me some help, ive searched but there isnt much info on this apart from "change the 02 sensor" which was just changed!

i know there are some hardcore honda gurus on here so help a guy out!

Have your injectors tested, check your Fuel pressure, and fuel pump. Thats your fuel system.
