O.K. Lets see who can figure this one out. About a year ago I replaced my exhaust from the headers back - y pipes/converter/Dynomax mufflers- and since that time I'm getting a strange odor at certain time. When and only when I start my car after its completely cooled off , I get a "rotten egg" type odor. This only occurs if the car is stone cold at start-up and the choke is on fast idle. At the same time my check engine light will come on. Once the car drops off fast idle, the light goes out and the odor goes away? This has only started since I replaced my exhaust and only at cold start-up. I had my mechanic doubled check the settings on my carb and he found everything to be ok. He scanned the ECM and the only code that is in the ECM is for a Vehicle Speed Sensor Fault, which I don't think would relate to my problem since the car is at a stop. I'm at a loss on this one, any ideas out there on the CAC.
