CEL when car reaches normal temp.

[ShawnsGarage]

When I first start up my car(engine not warm) I have No CEL. When the temp gauge gets right there at normal temp the CEL comes on. I know it has to do with emissions crap. I have a cat delete and removed all vac lines on the car. Could it be my oxygen sensor? Also exhaust smells like raw fuel so thats why i suspect o2 but just wanna know yalls thoughts.

Have you ran it thru a computer yet? is there an exhaust leak? I recently had the same problem and i found a very small hole in the flex pipe.

I would say it is probably the o2. My car dose the same thing.

o2 sensor probably isn't cycling

Get a reader and see what code(s) it's throwing.

And your exhaust will probably smell of fuel because of the cat delete.
