When having a diagnostic run on my motor a while back, the tech said that the #2 injector was not operating as it should and may have to be replaced. When I crank the motor, it takes a few miles of driving before the motor runs with full torque. I guess it's getting time to change out the injector, but I don't have a manual to show me the #2 position. Can someone point me in the right direction? Driver/passenger side? 1st through 4th from front of motor? Also, are there any special tools needed to change out the injector? I'm guessing, pull the valve covers, remove old injector, replace with new. Sounds easy enough, but it seldom is. Thanks for your help. Brad
