fuel trims way + and then go - ??? ok so i went out on a ride and all my fuel trims were showing +4 to +9. after a little bit of driving they started to go back down around -2 to +2. the car was shut off and then sat a little bit and then we went back out. well at first they were really positive again and then they started to go back to normal.
what would cause this? just the car maybe needing to learn a little bit more? the tune was just put in the car today and we drove about 20 min. my only concern is this never happened before, but i figure its just a cold start/learning issue or something. let me know what you guys think

yeah they are active, but the vettes are hotter? i tried to adjust mine for better oscillations. what is the part number for the vettes? and are these the ones that eliminate extentions??
HumpinSS is using them he said they are much more active, not to sure if you do not need extentions but you have them anyway so you should be good there, I too need to pick up a set.. he knows the part# Ill pm him and get it for us I think he said they run about $75 each. at napa..
