I am confident we can resolve your problem together.Please remember I don't know your skill level. I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies to get to a satisfactory resolution.There will probably be some equipment needed for a proper diagnosis. If you are not comfortable with this or do not have any test equipment please let me know ASAP. I also try to give all of the information you may need expecting a positive rating. I am not compensated for my time until you leave a positive rating. Your rating should be based on the service you received.

What is the vehicle doing other than the P0300? Does it run Ok at idle? do you have a scan tool with DATA?

Hello, I have not heard from you in a few days. Do you still need assistance? I also noticed you haven't left a rating. I have assisted in good faith and am only compensated when you leave a positive rating. Please let me know if there is anything else you need to leave a positive rating. Conversations can always continue after a rating is received.
