OK, with this week alternating warm and cool temperatures I have more information to share. When the outdoor temperature is warm (55+) in the morning, I have no problems from the moment I start it up. When it is cool, I am still having the struggling issues. Any help at all would be greatly apprecaited, as I am new to this. I am planning to clean and replace the original MAF and the spark plugs and wires this weekend. Hopefully this will help. Thanks in advance.
