I'm not an expert or mechanic, but I think I know most terms by now because I've had this problem for a while now...
Here is the brief: Sunday I filled up the tank, and ti ran fine for 55 miles, after which it sat for 5 hours, and then turned on, and it REV'd up to ~3.5k before wanting to shift (i had to play with pedal & no CEL yet).
Then I parked it somewhere, adjusted the kick down cable, turned it back on which it now had the CEL on. It wouldn't rev up to 3000 anymore, but it wouldn't rev up to the regular 2k rpm before shifting to 2nd (hard acceleration/hesitation/low speed from stop/red light). All other gears seemed fine.
This morning, I drive 0.2 miles to the gas station, put 3 gallons in, and the car goes back to the ~3.5k rev before "wanting" to shift. It was fine after it shifted to 2nd and beyond.
And so I'm more leaning to believe that it only happens every time I open my gas tank door and stick it in (as wrong as that may sound)... Car is parked as I'm at work now, so I will update when I leave for home.
Any ideas on what it could be? I got the governor sensor/solenoid replaced.
Spark Plugs? MAF? TPS? O2 Sensor? Fuel Filter?
