slide the lower part of shifter handle down and you will find two screws, but there is 2 wires coming in from center console for overdrive button.you have to remove the center console cover and remove the 2 wires from connector and then pull up threw handle.when you go back together you will have to guide them back threw the handle.

My car is the same year, model and everything. I just bought a replacement controller on eBay. The LCD screen goes bad. It needs replacing. The unit is beautiful and guaranteed for a year.

Check your MAF and MAP sensor. The first 80% of your throttle signal from the TPS works with the O2 sensor to try to keep the air fuel ratio to 14.7 to 1 with the ECM controlling the fuel injector spray time and timing the ignition. After the 80% to WOT the ECM puts the O2 sensor in to an open loop and takes the Reading form the MAF and MAP sensor to run the engine richer so there will not be any Detonation to the engine and burning holes in the valves for running too lean. That is why it always feel like you get a little more when you ease off on the gas peddle from WOT. Recap check the TPS, MAF,and MAP sensor and wires to those sensors, if you can get the car scanned that would be great and you may find out which sensor may have gone bad, the other thing to is the fuel pressure regulator may be going bad and at WOT the pressure may be to high causing it to run to rich causing the loss of power. Good luck and hope this helps.

Not too bad. Not much room, just enough to drop the starter. It is probably easier to go up through exhaust if you can get your exhaust shield off the manifold .
