    Do you think it might be the temp sensor that you fixed?

    Re: Poor gas mileage/Sensors, please help a bit!

    I don't think that's my case. New symptom - from a dead stop, *sometimes* only when cold, I give half throttle and I get ALL EIGHT cylinders for about 5 seconds, then *insert fart sound here* back to 7 or 6 with a bad vibration and lack of power. I went to the junkyard today and got a used fuel rail, injectors, and wire harness from a DAMN good running Deville 4.9. I hope this will solve my problem.
