Is it too soon o too late? Did it suddenly change?

If you don't have a gauge, or you are looking for a roughly correct place to start, you can remove the cable from the throttle body lever, and adjust it so that the cable is neither slack, nor under tension when the cable is reinstalled on the throttle body lever. This will get you fairly close. We do not reccomend this for a final setting. You should always use a gauge to verify your TV setting.
With a Gauge
You will need to install your gauge into the TV test port on the transmission. The port is eight inch pipe thread, and is located on the passenger side of the transmission. Toward the back of the transmission, above the pan rail you will find two 7/16" headed pipe plugs side by side. One plug is level with the outer edge of the pan rail, and the other plug is recessed. The recessed plug is the TV test port. Since this port is recessed, you may not see it if you are looking straight up from under the transmission, you will have to try to see over the pan rail.
Remove the TV test plug and install the fitting for your gauge. Attach the line from your gauge to the fitting in the test port. With the engine running the gauge should read 0 to 5 pounds at idle. If you happen to have the special tool for testing TV pressure (installs on the ball end of the cable to pull it a measured amount), the reading on the gauge should be approximately 30 psi with the tool installed. If you don't have the special tool you can tape the gauge to the outside of your windshield with the numbers facing in and have an assistant ride with you to watch the gauge. Normal acceleration from a stop should produce around 30 psi. You also want to make sure that as soon as you start to apply throttle, the gauge reading begins to rise. This is a good indication that there is no slack in the cable. If you would like you can also check the WOT pressure with the gauge mounted this way, it should read around 85 psi.

Initial Adjustment A4LD
From under the hood, depress the D-flat while pulling the cable conduit out from cable body. See Fig. 3. Adjust cable by depressing accelerator pedal to floor.
