only one o2 sensor b16 swap?? help!! runs rich
i recently bought a 92 civic with a b16 swap in it- it is an SiR b16 supposedly converted to obd1 running a del sol ecu. It has a itr (4-2-1) upper exhaust manifold and the stock b16 lower(i think). It runs rich. I keep reading about 2 o2 sesnsors on these cars, but looking at mine- there are no o2 sensors on the upper manifold(i felt behind it and looked) where i usually see pictures of them . there is one 4 wire o2 sensor that is on the end of the header collector. there also seems to be some rewiring at the ecu plug (possibly for the single o2??)I'm not throwing any CEL's though. Have any of you ever heard of this setup??- could it be causing the rich mixture or any other problems- i will try to get a pic of the ecu harness - in the meantime- Any thoughts, suggestions????????
