I noticed that my upshift light turns on when I turn on the car, so I know the bulb is good, but it never comes on when driving. And I did test to see if it was just because I wasn't revving high enough, but all the way up to 3500 it didn't come on. Didn't think much of it but I don't know if its an indication of something important. Also, I was getting a check gauges light for a tiny bit of an instant when driving, and last night it came on for about 2-3 seconds. I checked all my gauges and my VMM and nothing seemed out of the ordinary... The car didn't run any worse when that light was on. Could this be indicative of a problem?
