ok so heres the deal, i have an 86 berlinetta camaro with one of those damn electronically controlled 4bbl q-jets. the car is running rich right now and i need to fix it up so it will pass the CA smog test. I know the air/fuel mixture is controlled by the ecm so my question is should i use a code reader to reset the computer or is there something else causing it (ive already checked all vaccuum lines and the pcv system, air filter is clean, ect)...Maybe a carb rebuild or just a new carb would help? any advice would be greatly appriciated
Thanks :-) |

i wish you luck! i bought a new q-jet it cost me about $440.00 and did not change a thing! run a diagnostic on it hopefully that will tell you something.

this is going back a long way for me, but look for a map/baro sensor...check to see the vac lines are good to it, and that it is functional...you can get a gm map sensor for about 40 bux...if you scan it, you can pull a data stream to see if it`s working...i`m sure the book gives a voltage test procedure also...it sounds like the auto enrichment valve on the carb is stuck open, either due to the ecm, or gunk on the valve...jm2c...
