Update on high RPM loss of power... I ran the car with the Cat un-bolted with no noticeable change, but when I pulled the spark plugs out to inspect and re-gap I noticed that 3 plugs looked a little "wet" from gas. The color looks good ( light tan ) so it doesn't seem to be running rich. My thought is that I may may have some fuel injectors that leak. It has also begun to idle a bit rough in gear and when in park the RPM seem to fluctuate slightly. ( maybe +/- 50 RPM's) Does it look like I am on the right track??? Thanks for any input...
