so i've been trying to pass emissions for the last few days but to no avail..

the first time around i had failed miserably due to bad cats, so i had that replaced.

second time, i barely failed with my CO reading too high.

third time, decided to change the O2 sensor and plugs and gave it a go. didnt bother resetting the ECU and of course, failed miserably.

after that, decided to reset the ECU and now my car is running like ****.

I've had the CEL light come on intermittenly, car would stall, and also stumble (followed by CEL light).

The car currently runs tooo rich (by smell of exhaust and also the backfiring on the car while at idle). Any ideas as to what my problem is? My car is 100% stock. :s

I'm bringing it in tmrw to a shop that deals with rotaries, but I'd like to at least get an idea of what's going on.

Any help would be appreciated. Thanks

i know this is always said... but... check the map sensor and make sure its vaccum hose is plugged in.. other then that, get it scanned and find out what the codes are.

omochi

well i checked the codes.. and it says the Water Thermosensor.

is this why my car is dying, not passing emissions, and running rich?

mad_7tist

yes. it will enrich the fuel because it thinks it is cold. what was the code #9?

omochi

yup, #9.

actually i just found more threads on this.. thanks for the help anyhow guys

i hope this will solve my probs!~

You might have killed your cat from running so rich.

It most likely will, after I replaced mine (throwing 9 as well) it passed emissions fine and was not dying nearly as much.
