wondering if somone can give me idea of what would cause this 1995 trans am runs lean on right bank around 150-160 left side stays around 128 and long terms are 128-128 since running like this car has new fuel filter, plugs wires, acdelo o2 sensers, as&m headers and y pipe, new injectors, borla catback 3.73 gears transgo shift kit , tuned by lt1pcmtuning. fixed broken check vavle. car still runs lean on right side only?

 

Misfires, exhaust leaks before O2 sensor, faulty O2 sensor or wiring (I assume you have extensions for the LT's).

Swap the two O2 sensors side to side. If the problem follows the sensor, its a sensor problem. If the problem stays on the passenger side its something else. Since they are new (did the problem exist BEFORE you installed the new O2 sensors), it's probably not them, but you need to rule them out.

Are you getting any codes (injector circuits?)?

You need to add a "Signature" with basic info about your car - year, model, engine, trans and mods.

 

yes i had this problem before i added headers, plugs wires, new o2s and o2 extentions. thanks for the reply. no codes coming up
