i have had this problem for about 3 months. The car misfire when there is a load on the engine but when i reved in neutral it wont misfire or bog. there are no codes that are showing i have cleaned the MAF that didnt help. i took it to a shop and after 100$ they told my that cylinder #1 and #5 are intermediate misfireing so i replace those injectors and still have the problem and that is where i am now. Can anyone help me!
