HELPP!!!!
Hey y’all, I recently had a short in my engine wiring harness, and it shorted the coil pack, so the car was misfiring on cylinder #4. I replaced the spark plug, added a new coil pack, New fuel injectors, and an exact same part number wiring harness ( new/used), but I am still miss firing on cylinder #4. My next guess would be the ECU because before it shorted, the car ran amazing, no leak, no problems, nothing. Any advice would be helpful. Thanks.
