so i went and got my z emissioned and here is what the results looked like....

HC GPM-9.9732 limit-1.500 FAIL

CO GPM-77.6806 limit-15.0000 FAIL

NOx GPM-0.0365 limit-3.5000 PASS!

I reall have no idea where to begin. .
Ive replaced just about everything... o2's, map, fuel press. reg., 26#injectors,
knock sensor, IAC, pcm, etc.

Any help is apreciated!!

 

it looks like you are either dumping fuel or your cat is dead or possibly hollowed out?

i would lean more toward a cat issue with the list of other stuff you have replaced.

 

High HC and CO, combined with very low NOx would indicate that it is running excessively rich.

 

yes very rich....
anything i can do to help this?

EDIT: also, would smoke from startup be a sign of a dead cat?

 

When was the last time you checked your plug wires? O2 sensors?

 

few months ago.

just heard from the shop and turnd out how i was using no stat made it pretty bad.
cylinder 4 spark plugs gap was bent so that explains the fuel dump...and the left o2 sensor is bad!!!

so i get to actually have 8 cylinders now come monday!
