Burning real rich

I recently swapped in a new cam, so I had to adjust the rockers of course. I also had my injectors cleaned. I would assume the computer would have adjusted to all this stuff since the cam is the emissions friendly ( and weak) powermax 2030.

I am thinking maybe one of the rockers has loosened itself since the engine just started burning this rich recently
OR
I replaced my O2 sensor in the spring, but didn't know not to touch the tip of it so I may have. I am thinking that if I did touch it, the oils on my finger would make the tip feel hotter so the sensor would think I was lean and give me more gas. Am I right?

so just to recap....no codes, and I'm running real rich

Seems like there's nobody on the boards lately ......maybe everyone is on their way to Harley's 100th anniversary party here in Milwaukee

How do you know you're running rich? Did you do a diagnostic with a computer, or did you read the plugs? How's your major tuneup status?

I know its running rich just because of the exhaust...it just smells like gas. I will check the plugs today. As far as a tune-up goes, Everything in the ignition has been replaced aside from the distributor cap and rotor,
I have done in the last about 700 miles
new fuel filter
oil change
tranny fluid + filter change
timing is at the stock spec....gonna recheck that tho
Injectors have been cleaned
I have k&n air filter
The only things on your list I haven't done are rear axle gear lube, distributor cap and rotor, and pcv valve

It seems to run the richest right after start up, for the first few seconds, and the revs jump around between like 500 and 1500 during that time
