[QUOTE="M.P. Cobra Fan, post: 9648933, member: 65099"] No Ideas? Here is a little more info that may help. When the plugs were changed, two looked like those cylinders could be running slightly lean. I put a scan tool on the car and repiclated the problem. No misfires in any cylinder. All injectors show to operate properly. I put an ohm meter on the injectors and all injectors are a flat 18ohms. I have seen where this could be an EGR problem or O2 sensor problem. Rear O2's are turned off. Front have never been changed, but show on the scanner to be operating. Did a manual draw on the EGR valve and it is operating. Could still be carbon buildup. I am going to try replacing the O2 sensors next and cleaning the EGR valve. The car runs fine under WOT, and only has this hesitation between the specified RPMs under cruising. Any other ideas? [/QUOTE]
