TBI: running rich

[yoshisv]

My Blazer has a 350 30 over with 262 xe comp cam, flat tops, k&n, helix power tower, chip, And flowmasters. I let it sit for a few months when the tranny was slipping, And ever since it smells like it is running very rich. It is so bad that it burns my eyes, And i can see it fuel smoking.

how should i go about fixing this? Can a bad oxygen sensor cause this?

Any trouble codes from the ECM?

I had a simlar problem, turned out to be the coolant temp senser for the computer.

is that a custom chip for the mods or just a reg stag 2 or something like that.

Sounds like that could be the answer.

It is a stage two chip.
It's not throwing any codes, So maybe it is the coolant temp sensor.

Thanks
