well a friend and myself dropped in a obd-1 gen1 b16a in my 1990 hatch.we left the car obd-0 also put in all the obd-0 sensor son the block.we ran knock,vtec soeloid and the oil pressure switch.we also are running a pw0 ecu and aren't throwing any codes what so ever.however we never did any second o2 sensor wiring/adding,still using only one.filled the car from empty w/premium fuel and my car has a very bad acceleration problem and deacceleration problem.rpm's take forever to rev up in gear or in nuetral.also the car sputters like its having trouble breathing or maybe some vacuum problems ? but we hoocked everything up correct.distributor is in good shape also the plugs and plug wires are of my previous running motor.any idea of some help ? thanks in advance.

 

Try running the other o2 sensor into the same pin because some people i know have done this and never had a problem since or get another o2 welded in.

 

i have an obd1 sirII b16a turned obd0 and dropped in my hatch.

I'm only using one o2, and mine ran better than fine, it hauled ***. your one o2 setup may be fine, but just have a bad o2 screwed into the bung.

think of that yet?

 

well we took most of the items from my previous b-series and used it on my new b16a swap.the plugs,plug wires,headers w/o2 sensor and a few others.me and my friend have read alot of how people had the second o2 wires in and it all worked fine and their problem was pretty much dead on to what im going through.how would i go about running the second o2 ? and i would assume i'll have to go buy a new set of headers that have the 2 o2 sensor areas. ? thanks for the replys.
