Yes, I felt the plugs looked good as well. Im pretty confident its not a vacuum leak I checked for vacuum leaks about a dozen times, the converters dont turn cherry red if the car sits and idles to temp and beyond finally the problem is only at cold start up. Its very strange and seems odd that after resetting the ECU the problem seemed to go away on the next cold start up and the stumble is far less than before resetting ecu. I ordered an Actron CP9135 so I can check which codes its throwing now. Considering ordering an LM-1, data logging software and doing a street tune. Need to check and see which is more cost effective between dyno shop tune or buying all the stuff myself.
