Hi. I was just messing around with my car (94 Z28 Camaro) and recorded a
tts data log. At 75MPH my
Fuel trim cell is 7
LTerm Counts 108(r)/108(r) @75mph....no noticable fluxuation
Sterm Counts 121(r)/122(r) and they fluxuate 121(r)/132(g) 131/133 130/132 all @75mph
(r)=red (g)=green

At idle the
LTerm is 111(r)/108(r)
STerm fluxuates 129(w)/126(w) 127(w)/124(r) seems the 2nd number is always white or red at idle...could this be a bad bosch O2? (2 months old) and would the plugs im running, the Bosch Iridium Fusion(4 arc) make it run rich for some reason? I will produce the datamaster file later today when im not at work.
Thinmgs that have been changed in the last 4 months. Injectors (from my 95 Z28), Coil, plugs, TPS, Knock sencer, MAF(from 95Z28), MSD cap/rotor, Both O2s, PCV...and i think some more that I cant think of....any suggestions?
I want to get the MSD6a, Blaster coil, and 8.5MM plugs here soon too.

 

If parts were moved from your old 95 LT1, what year car are you putting them on now?

 

oops..forgot to mention that. The car is a 94 Z28 Maro.
