I cleaned the MAF sensor and the EGR valve and took it for a test drive. I simulated a highway passing situation. It hauls @$$ and about 3 seconds after I let off of the accelerator, it skips and the skip lasts for about 10 seconds. This is driving me nuts. It has been doing this since a month ir two after I bought it in '07. I am so tired of it that I am thinking of taking it to a dealer. I just hate to get my head busted and my wallet emptied. Any other ideas?
