alright i just installed an air-fuel ratio gauge to my 02 sensor, the gauge works but now my truck is real shaky and it smokes black a little bit. if anyone can help me it would be great. the truck is shaky during acceleration.

 

you dont want to mess with those 02 sensers. let the stock computer do all that calculating.

 

you dont want to mess with those 02 sensers. let the stock computer do all that calculating.sounds like however you have it wired its confusing the rich/lean mixture.

 

Which wire did you connect it to? It shouldnt have messed with anything unless you cut a wire....

 

its connected to the black wire. the instruction said to connect it to that wire. if im not supposed to do that, then where should i connect it to then.. thanks for the help guys.

 

Sure you didn't put diesel in it?!

 

yeah im pretty sure but no seriously i think i just fixed the problem i just rewired the 02 sensor back to normal and now it seems to be running fine, do any of you guys know where exactly i need to hook the air fuel gauge to
