problems running rich??? pros help needed

[eclipse0508]

i have a 95 gs and i recently bought a mozart racing exhaust by konig......i have had it for 6 months now. right before i bought it i had the headgasket replaced and heads machined. Now i am noticing white exhaust smoke out the back. I hear that means im running rich? What could i do to fix this....any info would be great.

Thanks......

If it's white smoke it's coolant. Grey smoke is unburned fuel. I'd say it's coolant by my experience. is your coolant low at all?

I always think of more things after I post something. Anyway, there are a lot of frickin vacuum lines and one coming off could definetly affect the air/fuel ratio. I had two that popped off and kicked on my check engine light and I finally found them after a month of driving with it too rich. Search for them, they seem to be everywhere in these cars.

the coolant stays the same level...........and the check engine light never comes on. I have also been getting bad gas milage. any info would be great

vacuum line won't necessarily kick the check engine light but it would definetly affect gas mileage if it was running rich. O2 sensor could be the culprit also. That will often either make it run too rich or too lean, depends on the car though, they all act different. The o2 sensor is pricey though so try to find any vacuum lines first. If there aren't any I'd bet it's the oxygen sensor
