Joel, It is normal for the idle to vary while the engine is in the warm-up cycle. If the idle does not settle down ten minutes after a cold start your CO mix adjustment is out of spec. A problem in the fuel enrichment circuit can also cause this condition. It is normal for the oil pressure gauge to rise and fall with the idle speed. Whenever you start the car the fuel level reading will be lower than the previous start depending how much fuel you used during that period. If the level rises between trips than the Tankzilla should correct the problem. PS: for myself and the other list members who submit advice, please be more definitive with your descriptions. Is the idle "rough" or does it "vary"? Do you have a problem with the oil "light" or "gauge"? Accurate descriptions allows us to give you more accurate information which saves time, not only for you, but for us as well. Thanks for your cooperation.
