hey guys latley my car seems sluggish when its warmed up.
when i first start it it picks up pretty good, after its warm it seems to be sluggish.
Just recently started happening. Im thinking it might be my o2 sensor's because my gas milage went down about 5mpg..

heres the setup.
91 civic si
b16a obdo
no cel
evrything runs fine.
just seems sluggish past 2 weeks.
spark plugs, wires, cap is all good.

let me know what you guys think before i got out and buy 2 new o2 sensors.

 

How's the rotor under the cap on the dizzy? double check the timing also..

 

good
good

 

wiring harness ? who knows man.
obd0 b16's are the WORST

ive had one in two cars and hated it.

either convert to obd1 if you dont figure it out or just tuff it out until you can get another swap
