My mechanic did not put in my o2 sensors when he put my headers on. what big of a difference does this make?

 

how's your car run?

 

I gather that to be a rhetorical question?



to the OP

Seriously, get some O2 extensions and put them in.

 

Without them, your engine is going to run too rich.

 

well it does run ok but I can smell lots of fuel. its running rich.

 

do you really have the mods in your sig?

If so, then you must have a custom tune and now you don't have O2's ????????

 

Yea I have everything in my sig. just got the car built. Got it back about 4 days ago. I was in the process of moving and he did not have any extensions to hook up my sensors to my headers. Lol and no I dont have tune yet. I'm in the process of replacing the clutch then I'm getting it dyno tuned.
