- Road tested and verified concern. Scan tested computer control system for stored trouble codes. Found code P0301 misfire cylinder#1 and P0304 misfire cylinder #4 (history code) Scope tested ignition system patterns. Viewed the live data stream and verified the misfire on cylinder #1 . Removed the #1 spark plug and inspected, checks good. Removed the #1 ignition coil and tested for signal from the pcm. checks good. Swapped the #1 and #3 ignition coils. The misfire followed the coil. The #1 cylinder ignition coil has failed and will need to be replaced.
- The technician removed the failed #1 cylinder ignition coil and installed a new ignition coil. Cleared the code and test drove the vehicle. The misfire is gone. The technician found there is a tcc (transmission) shudder in third gear when the torque converter goes into lock up. This is indicative of a failing torque converter.
