i reclaced the 02 sensor and now my car runs good except it revs up and down for a couple mins. can i adjust somthing on my power fc to make this stop

where did you get the new sensor from and how much did you pay bro

i had it off another motor

Your up and down revs have nothing to do with your new o2 sensor. Take a look at your throttle position sensor.

I had this problem with my TII it was the TPS that needed adjusting



It caused my idle to flucuate up and down

If you have any problems though with your TPS, normally won't it throw a "check engine" light on?

cheak your map sensor...
