Car won't pass E-test - high everything at 25 mph and I've been over the intake a dozen times looking for leaks. No codes set, slightly wavering idle, biggest problem is at about 2000-2500 rpms when it has the symptoms of running rich. Plugs are carboned up a little with cylinder 1 being the worst and cylinder 4 being the best. Car starts first time but is gutless for the 1st minute or so (feels like it's running lean) until the o2 sensor kicks in. I've been over all the other normal tune up/ fuel injection stuff testing and swapping parts until I'm blue in the face. Exhaust system is almost brand new front to back ( done by previous owner). So, does this sound like it could be an exhaust leak?

Thanks,

Ron
