I Need Help
I Need Help OK so i just put stock LS6 heads, Fast 92 intake and throttle body on my 98 trans am. got in all back together and its over fueling on the passenger side.
My guy thats tuning it said the Passenger o2 is reading like its not pluged in, i think i was readying 455 if i remember corectly. He told me to make sure it was plugged in or replace it if it was plugged in. and replaced the plugs since they were fouled out It was plugged in so i bought a new one. the problem is still there.
I also replaced the O2 extension just to check it since i had one laying around. At this point i dont know whats wrong. any Advice?

Is your tuner using a wideband? 455 is not an abnormal narrow band reading unless your in pe mode. What extension are u talking about? Are u running rear o2 sensors up front? Too many variables here, could be a number of things. Did u use new intake gaskets, throttle body gasket, everything seated properly,
he was reading that on his computer and i dont have a wide band on my car so i dont think so. He said that that what it reads when its not pluged in sometimes but i have checked the connection several times
I changed out the o2 extension on the passenger side.
Im using just the front o2 sensor
i didnt use new intake manifold gasket because they looked good.
i ended up geting a make your own gasket kit from the store on the throttle body since hawks third gen(right down the road from me) was out of 92 and i didnt have time to wait to get one.

You really need a wideband. Ask him what the LTFTs are for each bank, and replace your intake gaskets regardless of what they look like, I can tell you that once you put new ones in, you will feel the difference when you drop the intake back on.
