I have a problem with my 97... First off it shifts a little too early. I looked on the scanner it will go to 0% throttle but about 3/4 pedal will bring 100%. at no pedal it is close to 0 and at 100% it goes to 3.78 and will go clear up to 4.15 full throttle. Am I having issues or did I forget a step when installing my new ecm? It was matching PN.
