2005 TB I6. Has developed a "miss". At speed it is not a problem. When bogging down up a hill it will "miss" a couple of times. It will also do it at a stop light. The miss is a sudden drop of 100 to 200 rpm. It might do it 1 time or 3 or 4 times. Then sometimes it does not do it. I have cleaned the TB and have no codes showing or stored. Have run 5 or 6 tanks of gas thru and my wife gets her gas at the same place so not an issue with the gas .99000 miles and I plan to change spark plugs this weekend. Any other ideas while I am in there?
