Hey guys. I just had a new symptom crop up today. When accelerating up to 70 to get on the highway I notice a slight dip or surge in performance. This only happens when flooring it. I have always thought that I might have some type of restriction. Does this sound like a good observation? I have done all the maintenance required up until now. No CEL is on and I have replaced plugs and cleaned TB. Let me know what you think. I have always had the feeling this truck was under powered a bit. The downshifting on the highway on flat road kind of alerted me that i might have an issue.
